Details
Trying to reach the far edge of the range with your 5.56x45 rifle? Then it’s time to set the ball ammo aside and reach for the big boy rounds by Black Hills Ammunition. These tack-driving 5.56 cartridges are just like what professional snipers would use in their delicate line of work – and now they can be entirely yours to marvel at!
Newbies often ask if the open tip match is a suitable choice for hunting or self-defense. They mistake it for the kind of hollow point bullet that’s engineered to deliver terminal expansion, which it is most assuredly not. The narrow opening in the OTM’s tip only exists because its precision-formed copper jacket was filled with liquid lead at the factory. The lead hardened in place so it could create a core that perfectly conforms to the jacket’s interior geometry, and without possessing any voids that could have harmed the bullet’s rotational stability.
This round’s bullet is heavy. A 77 grain projectile would ideally be stabilized by a 1:8”, 1:7” or 1:6” barrel twist. But once it clears such a barrel’s muzzle, it’s due to exhibit superior resistance to wind drift. Quite useful when you’re shooting outdoors, don’t you know.
Black Hills certainly doesn’t use previously fired cases to load this sharpshooter’s ammo. The reloadable brass cases’ necks were correctly annealed at the factory – they simply weren’t given a cosmetic polish afterward.

Q: 1) in the photos some of the brass looks tarnished or darker at the bullet end. Are these reloads?
2) is there a dollar amount of ammo that I can buy that the shipping is free?
Posted On: 4/29/2023 By: Alan D Landis
A: Thanks for reaching out Alan! This isn't reloaded ammo. This is essentially the most accurate 5.56 that Black Hills is able to make – loaded according to the same specifications as the ammo they provide to U.S. Armed Forces snipers. Military grade brass cases usually aren't polished for enhanced cosmetics, because the manufacturer wants to show that they were correctly annealed. In this case, the new case still has a little bit of discoloration to show that it was manufactured correctly. We do not offer free shipping.
Q: Are these magnetic? Also is there a way to see the ballistics of this round?
Posted On: 11/27/2018 By: NICHOLAS FECHTER
A: These bullets are not magnetic. These are top quality Sierra MatchKing 77gr bullets. I unfortunate was not able to locate any ballistics chart for them on Sierra or Black Hills website.
