I agree totally - I read about these 'problems' and wonder if there was a blind test, where the shooter didn't know if it was lead or copper they were about to shoot at a deer, would they walk up the dead animal and think 'that's exactly what I expected to see'
I can't help but think people are looking to inflate issues that really and truly don't exist. Or if they do exist, perhaps not to the level that people make out.
The trouble is all these alleged 'issues' are looked at subjectively and not objectively and nobody seems to have done a proper scientific study to prove or disprove them.
I've been on Barnes TSX for a number of years in my .300 Winmag and all I can say is they're superbly accurate and knock all deer down very effectively.
