I don't. It's the consistent relative under-performance, compared to .338s. Seen it too often to ignore some obvious differences in the expediency with which the game is disabled abd dispatched. It becomes apparent on the BIG big game. On deer, no difference.Chit happens period. Don't discard the 284/30 caliber options for big Hooved critters just from one or a few mishaps.
I don't discard them. They kill ground squirrels very effectively, even when the bullet is placed into the earth in front of them.
