Could you explain that further please. The modifying of the die? Not sure I follow that as to how to accomplish or why I would want to. Maybe another thread is needed for that.
I am sorry my wording upset you, it was not intended to cause a fuss.
The barrel on my GG is so accustomed to lead I am not sure I would purchase of of these new full pressure rounds, I have only shot 20 of the trapdoor rounds before switching exclusively to lead cast bullets, mostly the MBC 405 grain for hand loads and HSM Cowboy for fun (and some hunting) and HSM Bear for hunting. But had these been available when I bought the rifle I would have been more likely to stay with a jacketed bullet using the trapdoor for fun (and some hunting) and the full pressure rounds for hunting.
