This is a sharpshooter’s 5.56x45 cartridge. A sniper might use ammo like this while’s he’s on official sniper business, though we don’t really recommend it for self-defense for two reasons. First, its hollow point boat tail bullet is incapable of the terminal expansion that neutralizes a threat more effectively. Second, firing long-distance ammo kind of implies that the target is too far away to pose a threat to the average civilian.

What makes this 5.56 round so accurate over longer distances? Its HPBT bullet, most of all, which features a balanced jacket, narrow tip, form-fitting lead core and precision angled boat tail. Combined with Sellier & Bellot’s carefully measured propellant charge and consistent primer, a round like this is poised to turn any AR-15 into a highly faithful instrument.

This round’s bullet is also very heavy at 77 grains. That effectively reduces its muzzle velocity to 2,825 fps, and it also means you’ll get the best accuracy out of a 1:8 or 1:7 twist barrel. But its relatively great heft also helps the bullet retain more of its momentum over the course of hundreds of yards, so it hits its target with more energy and additionally resists wind drift better than the 55 grain bullets most AR guys are accustomed to firing.

Sellier & Bellot is headquartered in the Czech Republic. You won’t find steel anywhere in this round’s bullet or reloadable brass case, and its Boxer primer is absolutely non-corrosive.
