I have never had a set back on Speer GD or HSTs in .45, .40, 357sig or 9mm, I check them regularly. I wonder how many bullets are shot that way. so many people seem to have it happen but the only way they find it is if they unchamber it.
there were posts here at one time that said top ammo manufactures concider this when working up loads but but many boutique ammo manufactures don't. that is where these smaller ammo companies get their extra speeds over the big ones.
