308 Win – 147 gr FMJ-BT – PMC (308B) – 20 Rounds

A single box is often all you need to function test a new 308 rifle, check a scope mount, or try a load before buying more. This listing is PMC Bronze 308 Winchester 147 grain full metal jacket boat tail ammo, MPN 308B, sold as one 20 round box for range days, rifle break-in, and comparing ammunition in your gun.

PMC rates this load at 2,780 fps with 2,522 ft-lbs of muzzle energy. The 147 grain bullet weight mirrors the military M80 ball load, so it gives a realistic training feel in semi-automatic battle rifles and bolt guns alike. The boat tail base improves the ballistic coefficient compared with a flat base. Because it is a full metal jacket bullet, it is meant for target shooting and practice, not for hunting, where a soft point or polymer tip bullet is required for clean kills.

This ammunition fits rifles chambered in 308 Winchester, including the Springfield M1A, FN FAL, DPMS and Aero Precision AR-10 pattern rifles, Ruger American and Ruger Precision Rifle, Remington 700, Savage 110 and 10, Tikka T3x, and Browning BLR. A common question is whether 308 Win and 7.62x51mm NATO are interchangeable. Commercial 308 Winchester is generally safe in rifles chambered for 7.62×51, and most modern 308 rifles fire 7.62 NATO, but chamber specifications differ slightly, so check your rifle maker’s guidance. Another common question is whether this load is good for a new rifle break-in. Yes, inexpensive brass-cased ball is a common choice for those first few hundred rounds.

PMC 308B is new production ammunition, not reloads, loaded in South Korea. It uses reloadable boxer-primed brass cases with non-corrosive primers. This listing is one box of 20 rounds from a single lot. If it groups well in your rifle, note the lot number on the box so you can try to match it when you buy more.
