Thanks for the reply. I’ll just have to do my own testing if the opportunity presents itself.
Why don't you learn how pre-test bullets in different kinds of media, rather than testing them on big game "if the opportunity presents itself"?
There are various things at work here--including the fact that cup-and-core bullets tend to expand and penetrate more reliably at moderate muzzle velocities--which has been widely know for a LONG time.
I have published a bunch of articles, and book chapters, on the various aspects of this subject. You might want to read some of them, rather than expect field results for every bullet from every cartridge on every kind of big game.
Maybe I'm little testy tonight, but there it is....
