That bullet that we make is designed so that if the nose does happen to shear it still weighs about 300 grs & that's a lot of bullet weight going forward. But with this Miha bullet it's easy to change pins & make it a solid that comes out about 410 gr depending on alloy. We've had exits on mature Bison with HP's.
The trick, if you want to call it that is to drive it the correct velocity for the alloy you're using when shooting HP's. Over drive them & you can make them fail. Mark, sent you a PM.
