actually you'd think so.......but it was a 45/70 at about 1900fps, and a 475 at 1350 or so fps.

i've pushed the beartooth over 2300 out of the rifles with no ill effect hitting large bones in animals over 1000lbs. i regularly push 340gr beartooth's out of a 454 over 1800fps and have never had a failure. i've tested both after the 475 failure in piles of gravel, water jugs, sand into wood and the beartooth do stay together much much better. the 454 load in question above i've shot stem to stern through a 2500lb bull so penetration is surely not an issue.
