Ok, I been on the search for à slug too that will accurately shoot out of the FX .357 mk2. So far the 81 grain pellet is confirmed to perfect but WE WANT TO USE SLUGS. Check this out y'all, I put the new 72cc plenum on my mk2 .357 and got it to push out the 81 grain pellets at 940. So what does that mean? I know slugs with high BC loves high FPS. I'm thinking maybe the 79s, 85s and 93 will work if yall install the 72cc plenum in. Yes, FX at this point has left us bogus with no slug liner,slugs or barrel tuner so we gotta do what we gotta do.
