I have had the same problem in one revolver I have. It is a Beretta Laramie in 38spl.

Mine rolls too far to the right (from the rear) and Magtech primers will not ignite. Wolf will. What I did was put the headstamp up, so when the round was in "battery" so to speak, I could tell which way I was out of alignment.

It was a fault with the firearm, not the ammunition. Run them through another firearm and see what they do.
