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.
