Never thought of that. Paper patching might work, but the next step is I wonder if it would be possible to bump up a 180 grn 357 slug to 366. It is only 9 thou. mmmmmmmmm.. A mate of mine bumps up 300 458 to 500 for his black powder express and it works. The slugs look very strange but they seem to shoot well enough to use the rifle. Keep us informed of how it goes.
