Has anyone used the 200/450 conical black powder pistol bullet? I have used the round ball and it is a 451 and you get a ring when putting it in the cylinder. I am planning to pc some of the conical bullets and wonder if they need to be sized to 450 after pc or if they need to be resized at all. If I go to resizing to 450 I will have to order a special sizing die because standard die is 451. Has anybody done this before? Thanks
