Folks I'm trying to load the lee 7/8 slug with a published load. The load was a cheddite hull with a LO78 wad, and 29 grains of green dot. I had wheel weights with 2% tin in my pot already so I cast some up. I tried to push the slug and wad down my barrel and it wouldn't fit. It's a improved cylinder choke. I had some old aa wads and it fit. So I measured the 2 and there was about .009 thousands different anyone have any ideas
