10, the thing that I have thought about many times, why does this not happen with the big cased .22's.. One thing I considered is I have never shot an animal except varmints at over 200 yards with those.. But most of my game with the .24's & 25's have been less than 200 also.. Thanks for the interest...
It may be due to higher velocity at impact and thinner jackets that you're just getting better/ more consistent expansion from the .22's. In the case I related above, I'm quite positive that core-lokt .243 bullet expanded very little or not at all. Also being well stabilized and penetrating through low in the chest, that bullet probably didn't have time to destabilize and tumble before exiting the far side. I have found the various 55 and 60 grain .22 caliber sp bullets I've used out of my.223's and .22-250's to be very destructive to the internal organs of deer on a consistent basis.
