This is the same exact 7.62x51 ammo the U.S. Armed Forces would use in their M240 and M60 machine guns, as well as their M24 and M110 sniper rifles. Now, to be sure, the 7.62x51 is actually loaded to a slightly lower pressure than the commercial 308 Win. That means if your rifle is capable of chambering 308, it can handle Lake City’s mil-spec ammo like a champ!
This round is equipped with a 149 grain full metal jacket boat tail bullet, thus earning it the M80 designation. In combat it would be the bullet you’d rely on for engaging enemy personnel and other unarmored targets. Such a non-expanding projectile makes a great choice for range training as well, especially thanks to its tapered base which serves to keep its trajectory flatter and its velocity faster over great distances.
We’re often asked if the discoloration around Lake City’s cases’ necks is a defect. Quite the contrary, as a matter of fact! The grayness simply indicates that the brass has been properly heat-treated to make it more supple around the neck. That helps the brass expand properly during ignition (which prevents carbon fouling of the action), and also makes it better for the reloading bench. Commercial factories heat-treat their brass in the same exact fashion, they just polish it up a little afterward to make their ammo look a little more presentable.
These rounds’ propellant charges and Boxer primers are both military grade. They’re the pinnacle of dependability, although reloaders must take note that Lake City’s primers are crimped. One more step at the reloading bench, but we’ve never felt we spend too much time reloading anyway.
These 350 rounds are stacked tidily together in a mil-spec steel ammo can (either a metal 30 cal can or 50 cal can depending on which batch it is). It’s a handy bit of hardware that seals up tight to keep ammo nice and fresh, and you’ll definitely want to hang to it long after you’re done with all this great 7.62x51 ammo!
