- Q & A
See the green paint on this round’s FMJ? That’s proof that its core contains a steel penetrator tip, which enhances its ability to pierce sheet metal and other common urban barriers. Just take care: Though the penetrator bullet can make short work of lightly armored threats and car doors, it will also attract a magnet and damage steel plate targets.
The M855 bullet is a little heavier than normal at 62 grains, which promotes greater accuracy over longer distances. You’ll want a barrel with a 1:8 or 1:9 twist if you want to see this ammo’s best accuracy for yourself, although a 1:7 twist is great for anything other than long-distance sharpshooting.
This NATO spec ammo is loaded with non-corrosive Boxer primers, low-fouling powder and factory-fresh brass cases. Lake City doesn’t care so much about cosmetics, which is why this ammo’s cases are still gray around the areas where they were strengthened via heat treatment.
