I have a sorta "odd" rifle. I have a 50/70 govt .510 grove built on a Ruger #3 receiver. I'm wondering about a gas check designed bullet in the proper diameter. My thoughts are by having the gas check in place I could do away with the wad stack in the case allowing more powder capacity. Trying to eek out as much space for blackpowder in the case. Anyone doing this? Or am I way off base.
