WELCOME

to Rolling Bones Precision All of us at Rolling Bones Outfitters (RBO) would like to extend a warm welcome and thank you for attending the Rolling Bones Precision (RBP) Hunter 1 course of instruction. By investing your time and money to receive training, whether here, or any other marksmanship course, you display the straights of a true hunter.

Training and preparation are fundamental aspects of a positive hunting experience. Guided hunts are an investment of time and money as are DIY hunts. If hunters are not prepared, the odds of lessoning the overall experience that you pay for are increased.

Many of you have heard hunting stories of the one that got away and normally there was always something that went wrong other than the shooter making a mistake. The reality is, and this is a very hard pill for some to swallow is that almost always missing or wounding an animal is shooter error. This course is designed to teach you as the hunter to take full responsibility of the bullet from the time it leaves the barrel until the second it accurately reaches its final destination. Most importantly; based on your training and experience you will know when NOT to take a shot and risk wounding and losing an animal. Now prepare yourself for great times, great camaraderie, and burning of lots of gunpowder.

This course of instruction is not a long range shooting course. This is a precision shooting course for hunters.

Overview

“

RBP wants to stress that this course of instruction is not a long range shooting course. This is a precision shooting course for hunters. Different conditions, abilities, equipment, experience, etc… mean not everyone will be the same..

Many believe that in order to shoot at extended ranges you need an uber accurate rifle. An accurate rifle is necessary, but equally or possible more important is the precision of the shooter and shooting system.

We will cover: Safety- Whether in the field or at this course we will practice in a safe manner at all times.

The Rifle- We will cover the rifle and give you the confidence to continue your journey with marksmanship The Scope- This is of utmost importance in our shooting system. We will cover nomenclature, and functionality: pro’s and con’s of different scopes, zeroing, and adjustments.

Ballistics-The effects of atmospherics, their affect of the bullet and how to adjust to differing conditions.

Ranging and DOPE- How to obtain the range to the target and obtain a firing solution.

Fundamentals of Marksmanship- Marksmanship methods to increase your confidence and abilities Cleaning and Maintenance- Methods and materials used as well as how to…

Safety As shooting instructors, we spend a significant amount of time on shooting ranges. This puts us at increased risk if proper safety protocols are not followed.

Safety rules will be rigorously followed at ALL TIMES! Please keep your muzzle pointed in a safe direction at all times. A momentary lapse in judgment could have deadly consequences.

one

FOUR TENETS OF FIREARM SAFETY

Treat all guns as if they are loaded

two

three

four

Never let the muzzle cover anything you don’t wish to destroy

Keep your finger off the trigger until you are ready to fire

Be 100% sure of your target and what is in front of and behind it.

Transporting your firearm: While at RBP, all firearms will be transported completely unloaded. This means the chamber is clear, and no rounds in the magazine.

Safety at the Range 1. Never load you gun until the Range Officer (RO) instructs you to do so 2. When on the firing line, muzzles must be pointed downrange at all times.

3. Do not go in front of the firing line at any time even if the range is cold unless the RO tells you it is OK 4. Guns will be clear, safe and bolts open and to the rear before anyone goes down range 5. DO NOT touch your gun on the firing line while someone is down range

6. If a gun must be worked on, move to the designated area, and ensure the gun is clear prior to leaving the firing line.

7. The RO will declare the range HOT or COLD. Guns must not be loaded until the range is HOT, and when the range is COLD guns must clear, safe and the bolt open and to the rear.

8. When the RO declares “RANGE IS HOT, or RANGE IS COLD,” all shooters will Loudly repeat.

9. Safety is everyone’s responsibility and anyone can call a cease fire at any time and for any reason.

Dial & Dump System

This is your opportunity to take your favorite rifle and turn it into an extended range hunting system.

How it works You send us your rifle with your current mounts and two boxes of ammo (that you hunt with). We will take your rifle and go to work! This will include us mounting and leveling your scope, installation of a scope level, collecting your data, creating a turret with bullet drop compensation to match your bullets, sighting it in for zero. We also have to install a cheek piece on your rifle to aid you in the proper cheek weld. We then box your rifle system and return it to your FFL of choice and you’re ready to go range, dial and dump on your next adventure.

Cheek Piece

We do the work to calibrate your rifle to your ammo with our shooting system.

This customization system has been proven at Rolling Bones Outdoors with nearly a half-century of extended range shooting and hunting experience. Our goal is to provide and deliver you a better down range experience.

The Rifle BARREL- Many different options from material, thickness, twists, rifling, different crowns, muzzle brakes, suppressors etc…

Pro’s and con’s of Carbon Fiber barrels Pro’s and con’s of SS barrels Chamber and it’s effect on accuracy RIFLING AND TWIST RATES- Lands and grooves help to stabilize the bullet as it leaves the barrel. The proper twist is required to stabilize the high BC bullets that are used.

Without rifling your bullet would immediately start to tumble. You will want to know the twist rate to input in your ballistic app and is either listed on the barrel or is easy to obtain.

STOCK- The stock connects the receiver and the action. The stock is one of the most under appreciated aspects of the shooting system.

A good, high quality stock of the appropriate engineering aids in your natural point of aim, shoot ability, trigger control as well as recoil management. We ALWAYS want to have the ability to attach a bipod to the front of the stock.

We also want to be able to have a sling on our stock. We much prefer a vertical palm grip on our stocks which increase the chance of have straight line pressure on your trigger. It also aids tremendously in recoil management.

RBO Ovis Shooting System

RECEIVER- The receiver is the heart of the system. The receiver connects the barrel, bolt, trigger, safety, stock, and rings to the optic. A custom or “blueprinted” factory receiver have tighter tolerances than a stock, factory action and increase the odds of better accuracy.

Rifle scope

RBP Mountain Shooting Course

A riflescope used for extended range shooting has numerous requirements. A high quality riflescope is imperative to successful application of the dope required to hit at extended range.

Erector Tube This the main body of the scope. In the scopes we usually use comes in 30,34 or 35mm’s. The larger tube dimension allows for more elevation adjustment.

This is what dimension your scope rings are for.

ocular lens This is the lens closest to the eye. This is where your reticle focus is adjusted. This traditionally has to be done to match your vision only one time. Many scopes have a lock ring once this is properly set.

Some scopes have better engineered Ocular lens’ than others and are easier to properly get oriented with in shooting position. This is what is referred to as a generous eye box.

Objective Lens This is the lens towards the muzzle of the gun. The scopes that we use typically have at least a 44mm objective lens and go up to 52mm or greater.

ELEVATION AND WINDAGE TURRETS These are the turrets that move the reticle up and down as well as left and right. The amount of movement is calibrated in specific units. The most common units are MOA, MIL, 1/4” per click etc… We use MOA’s and usually it’s 1/4 MOA per click and try to not go with finer adjustments or more coarse.

Reticle The reticle is what you see when you look through your scope. There are many different styles of reticle. We find it VERY useful to have the ability to have a constant marked reticle that allows for use in holding wind, adjusting for follow up shots, measuring objects and even ranging. The reticle that we most commonly use has graduations evenly distributed 1 MOA apart on the horizontal and vertical axis.

Remember RETICLE=RULER

Parallax Adjustment

TURRET

Traditionally on the left side of the riflescope, but not always. If the reticle and the image are not on the same plane this allows you to coincidence the images.

The turrets the raised knobs typically on top and the right side of the rifle scope. They are used to change the bullet impact by raising, lowering or shifting right and left the reticle.

They are oftentimes called Elevation and Windage knobs.

Remember TURRET=TWIST

Zeroing and Adjustments We obtain a good zero at 100 yards. We want accuracy and precision. Try to shoot as tight of a three shot group as possible. Once you have obtained a good group we adjust your groups point of impact to your point of aim. This is very important to have your point of impact the same as your point of aim.

If they are different it is easy to measure with your scopes reticle and make the necessary adjustments. At this point we slip the turrets, which means that we set the windage and elevation turrets to their zero. From here we can measure from zero the data needed to correct for the point of aim at different yardages. We will record this information in our data books.

We will measure all of our information in Minutes of Angle (MOA).

An MOA is an angular unit of measure that works very well with extended range shooting. To break this down so we understand it, let’s look at a circle.

A circle has 360 degrees in it. A degree is comprised of 60 minutes. Think of a MOA similarly to a minute on a clock. A minute of angle is one sixtieth of a degree, as a minute on a clock is one sixtieth of an hour. A minute of angle is an angular measurement, but it is easy to think of its angular dispersion at different ranges in terms of inches.

An MOA at 100 yards is the equivalent to 1.047 inches at 100 yards, which can be simplified down to 1 inch at 100 yards. At 500 yards, 1 MOA is 5.235 inches. At 1000 yards 1 MOA is the equivalent of 10.47 inches. To simplify then, 1 MOA at 100 yards is roughly equal to 1 inch, at 500 it is roughly equal to 5 inches and at 1000 yards it is roughly equal to 10 inches.

From here forth all of our measurements will be done in Minutes 360 Degrees = 21,6000 minutes of Angle (MOA.) 1 Degree = 60 minutes 1 MOA = 1/60th of a degree

MOA = Minutes of Angle

Anatomy of a long-range shot THE FIRST THING YOU WILL NEED IS AN ACCURATE RANGE CALL In order to perform a shot that is beyond the distance of what your reticle is zero’d at several things are required. Without these few items an extended range shot is simply not predictable.

First an accurate range call is required. The simplest and usually most effective way to do this is quality rangefinder. Other options include ranging with your reticle, GPS etc…

Secondly, you must know the ballistic curve of your rifle. This information is essentially the Ballistic Coefficient, Muzzle Velocity of your ammo, etc…

Gravity is a constant, which is measured at 9.8 m/s/s DOPE- Data Obtained on Previous Engagements: These are the come ups from your zero required for varying ranges

DOPE = Data Obtained on Previous Engagement

RBP Mountain Shooting Course

EXTERNAL BALLISTICS GRAVITY

Once you fire a bullet, gravity immediately begins to pull a bullet back towards earth. This is a reliable constant (gravitational acceleration) of 9.8m/s/s or 32ft/s/s.

AIR DENSITY

TERMINAL BALLISTICS Terminal ballistics is the study of how the bullet effects the target. The main thing is to hit the vitals. Also of tremendous importance is how the bullet damages tissue in game animals. The permanent wound cavity is essentially what tissue gets destroyed by the bullet as well as any bone etc… an expanding bullet creates a more significant crush cavity than full metal jackets or the like.

Monolitic or stout bonded bullets are a blend.

This is unsettled science, but at RBO we have thousands of experiences and we strongly lean towards fragmenting expanding bullet.

This is the measure of air pressure, temperature and the humidity of the air that the bullet must travel through. Air pressure is referenced as Barometric Pressure or Station Pressure. We will be referencing station pressure, which is uncorrected air pressure.

Barometric Pressure is corrected for sea level and the standard is 29.92 at 59 degrees. We will be referencing inHg as our units of measure but their are others like psi etc…If we use station pressure the altitude is not required because we use the actual uncorrected pressure so we know the precise value of the air resistance. If we use Barometric pressure then altitude must be included in our equation. Tools to measure Station Pressure include, Kestral weather stations, watches such as ABC sensor watches like Suunto or Casio’s, and many of today’s rangefinders incorporate weather stations onboard with ballistic programs.

BALLISTIC COEFFICIENT - (BC) This is a numerical value associated with the ability of a bullet to withstand air density. The higher the number the better. Their are different standards used to measure BC’s but we usually reference G1 and G7.

Muzzle Velocity How fast the bullet is traveling. Faster is good but minimal variation is more important. The faster the bullet is traveling the less time the air density has to effect it. The more consistent the bullet is traveling the lower the dispersion of the bullet fan will be. We strive for a Standard Deviation of 10 FPS or lower.

Weather Temperature- higher temps lead to lighter air. Humidity- Higher humidity leads to lighter air. Wind- The most difficult part of external ballistics. Wind upon the bullet pushes the bullet and must be accounted for.

The wind must be accounted for all the way from the muzzle to the target. Weather stations can help at the muzzle, but other indicators like mirage, and reading vegetation along the bullets path will also be incorporated to come up with a solution. One of the main reasons that we try to use bullets with higher BC numbers is to lessen the effects of wind on our bullet.

DOPE AND VALIDATION As mentioned earlier, DOPE is an acronym for Data Obtained on Previous Engagements. This is the measure of how much we need to adjust our scope from zero at different ranges. There numerous ways to acquire your dope. The traditional way and still a very good way is to simply shoot at various ranges and record the data. This has some limitations, such as time, volume of components and varying atmospheric conditions. After you have done this and are comfortable with this traditional methodology you can also obtain a good zero: then use a ballistic ap and based on your velocity, BC, atmospherics compute the DOPE. You must then validate the data and adjust accordingly.

When you get solid reliable DOPE, the elevation component of long range shooting becomes consistent. It is just a number. The wild card of this process is Wind.

Range card

& bALLISTIC APPS RANGE CARDS ARE ESSENTIAL TO HAVE AS PART OF YOUR GEAR.

We believe they are so important that we go so far as to place a copy of the range card - on the turret. We believe the range card is so important that we have a copy of it right above the MOA’s on our turret, which greatly speeds up the process of converting range to MOA’s. This allows us to simply Range, Dial and Dump (as in the animal, not the kind that requires TP.) We also carry a backup hard copy with us.

Our hard copy is a little more elaborate and rarely gets used.

We also have the electronic copy on our phone in the form of a Ballistic Ap. The favorite two that we use are Shooter and Hornady 4DOF. Shooter is $10 and 4DOF is free.

In addition to those we usually have rangefinders with built in weather stations, and ballistic programs in them. In the coming years this will become more and more standard.

We use, Leica Geovids, Leica rangefinders, Sig 2400’s, Sig BDX, Zeiss Victory RF binos, kestrels with ballistics on board ( AB or 4DOF.) These compensate for angles, differing atmospherics and make things go much faster in general.

Fundamentals of marksmanship The fundamentals of marksmanship are key to successful shot execution.

Obviously your rifle must be zeroed, and you have to know the ballistics the range and the atmospherics. After that employ the fundamentals of marksmanship and “Send It.”

STABILITY The proper shooting position will allow us to get as Stabile as possible. If you can get prone, that will give you the most stability to execute your shot. This is common sense but not always followed. Sitting is the next best way to increase your stability followed by kneeling. The least stable position is freehand.

With all of these positions, their are ways to increase your stability and therefor your success. The more bone on bone opportunity you have the more stabile you will be. It is also important for your muscles to be relaxed. With relaxed muscles you will be able to achieve a Natural Point of Aim. We will get back to this later.

SIGHT ALIGNMENT Center the crosshairs on the target and let your eye focus intently on the target. It is important to not have any uneven shadowing in your scope. Ideally you will have a very clear sight picture.

BREATH CONTROL It is important for you to execute the shot at a predictable point in your breath cycle every time. A common approach is to squeeze the trigger at the natural respiratory pause. During your breath cycle do not hold your breath for an excessive duration. If you do, it is is best to start your breath cycle over and find the spot in your natural respiratory pause that’s comfortable to execute the shot when you are ready.

TRIGGER CONTROL While doing all of the above, this is where the rubber meets the road. A friend of ours stated this is where you are either a hero, or a zero. Proper trigger control means that you maintain a proper sight picture, and under control gently press the trigger until the round fires. The force vector of your trigger finger should be straight back towards your shoulder. Any deviation other than straight back can move your reticle off target resulting in errant shot.

FOLLOW THROUGH This is important for many reasons. You want to maintain the rifle on the target as long as possible ensuring that the rifle stays on target while the bullet clears the barrel. Proper follow through also helps with recoil management. Once you squeeze the trigger: hold the trigger momentarily cycle another round, stay in the scope and re-engage the target. With practice you will be able to spot your shot.

There is benefit to this, you should be able to follow through and make any necessary adjustments for a follow up shot need be. Remember the reticle is your ruler, use it.

NATURAL POINT OF AIM “

...the gun must naturally, andwithout effort, be pointed on target.

“

Natural Point of Aim is immensely important. Hopefully the ergonomics of your rifle system will enable a more natural point of aim. When you look through your scope, you should naturally see your sight picture naturally. Tight or tense muscles inhibit this. Everything should be relaxed, Jabba-the-Hut-Amoeba-like. You must build your position so that your gun naturally sits on target. No matter what the condition of the shot that presents to you, the gun must naturally, without effort be pointed on target. This also allows for a more effortless follow up shot as the rifle tends to fall back on target.

CLEANING & MAINTENANCE “

With continual shooting the accuracy of your rifle will diminish.

“

We like to clean our rifles on a schedule so as to not reach the point of decreased accuracy. With enough rounds, the degradation becomes significant.

Another thing to consider is suppressor use.

Suppressors increase the back pressure and make a noticeable difference in your cleaning schedule.
