Re: 270 wsm on coues deer
Be ready for some extreme energy displacement if you go with the b-tip.
I've shot 3 coues with 130's from a 270 WSM and lost no meat on one, one quarter on the second and three quarters on the third! Was the spotter for another (same caliber) and it turned the on side quarter inside out. They tear stuff up!
Farthest of all shots was 247, so the speed was still way up.
The up side is the farthest any of 'em went was 150 yards.
The b-tips work, but expect some meat loss if not put in the ribs.
