BULLET BULLETIN Hornady’s engineers made revisions to the GMX bullet to arrive at the new CX bullet.
GOING FROM GOOD TO GREAT
Hornady’s new CX expanding copper bullets are a step up from their GMX line and a solid choice for pursuing big game where lead-free ammo is required.

here is no doubt about it: the lead-free monometal bullet is here to stay. It is a legal requirement in the state of California, and my home state of New York is pushing to require lead-free ammunition on our plentiful public lands. Whether required or not, the lead-free copper alloy

projectiles offer excellent performance, with the rifle bullets giving deep penetration with high weight retention; there is no jacket and core to separate. While Hornady was not the first to develop a successful monometal copper alloy projectile – that distinction belongs to Barnes – they have, like many other companies, developed a great monometal. Their GMX – standing for Gilding Metal eXpanding – was equipped with the
signature Hornady red polymer tip over a hollow cavity; during flight the polymer tip helps to maintain a consistent ballistic coefficient, and upon impact, it acts as a wedge to initiate expansion. The GMX was a good bullet, and proved to be accurate and consistent in both component form – where I handloaded it in a whole bunch of different cartridges – as well as the Hornady Outfitter and Full Boar lines of factory-loaded ammunition. americanshootingjournal.com 65
