I'm curious as to the different performance? Do they penetrate deeper/hold together better?
The ones I shot with the 18 inch suppressed MK12 SPR, the 77 TMKs went into the lung, 22 hole, and about 3 inches it exploded, just like what I've seen with Bergers. No exit wound.
The 2 I shot dropped, similar to what you see with CNS shot. That would most likely not the norm, hard to predict how an animal would react. Plus, data is too small to make any meaningful conclusion, it is what it is, simple anecdotal evidence.
