Thread: 45/70 Subsonic

My Marlin 3030 has a micro grooved barrel, is your g/gun the same, I`m trying cast in my 3030 but not much success with a 150gr gc bullet. I think a 170gr would better, may have to ream out the mould a bit. In the light loads with the 45-70 are you using a filler or wad to keep the small powder charge by the primer. I only like to have two powders, 3031 for my .308, 3030, 45-70 and black also for the 45-70 so there's no mistakes. And it`s so much fun when I`m at the range with my Sharps and there`s all the semi autos in .223 with a big muffler on the end and I let rip with a black powder load,
