I'd guess that reported bullet failure of PB"s are mostly caused by poor shot placement or guys stuffing too much powder behind a pure lead bullet.
It doesn't make much difference what design a pure lead bullet has, pure lead can only so much.
I have killed deer with patch round balls, Maxi Hunters and 295gr PB's. Elk I have killed with Maxiballs,295 gr PB"s and 348 gr PB's.
The problem here of guys complaining about them is the muzzle loader season is suppose to be a primitive weapon season and guys want the muzzle loader to perform the same way a center fire rifle does.
When you think about it,the same problems surface with the center fire bullets. Poor shot placement or driving them faster than they were designed for.
I could take a 1/2 " diameter lead rod and cut it to the appropriate length and go kill elk and deer with it. Obviously there are people out there that can't.
