I am not going to take one side or the other about "energy transfer". All I want is a clean kill and then be able to find the darned thing. In my book, an exit wound at the least adds the possibility of an addition "hole" leaking blood. As far as wound, from a 243 Win. up, for sure, ain't no deer in the NA woods that can survive a 2X expansion of a quality hunting bullet if that bullet passes through the engine room. Might run a 100 yards or so, but it'll be as dead as Jimmy Hoffa in only a handful of seconds.

Chest shots with a 45.70 Gov. at 25 yards! Are you kidding me !!! May as well have detonated a grenade in that deer's chest ! That 50 yards was nothing less than a "dead deer running".

If you want to try another factory load, look at the Hornmady Leverlution. I switched to it in my 444 Marlin and am very pleased with the performance.
