Thanks
I am sure that with the size of the case being bigger that the regular Sherman should use more powder. I have been talking to a few people and think I will start out fire forming my brass with 23 at somewhere around 57 to 58. I haven't decided yet what I am going to use for fireforming as far as the bullet. I have alot to choose from. From 107,120,142 SMK to 123, 129, 147 Hornady. Probably 107,123 or 129 since I don't use these in anything else anymore.
