I loaded up some Sierra 85 gr HPBT for a 243win several years ago after all the positive reviews I read. I shot a buck at under 75yds his back feet came straight in the air and when they came down he took off, 3 of use searched 2 hours before it got dark and 3 hours after dark, went back and searched 4 more hours the next morning, never did find it. The rest of the ones I had loaded up, near 100 of them made holes in paper and I reloaded them with hornady 100gr sp and no more problems like that.
