I have been looking at 410 shotguns lately and I am wondering about crafting some slug loads. The factory loads are worse than anemic unless someone knows of some that are better than 1/5 oz. I have seen some info on 147 gr wad cutters in .357. Single and double loads. The 410 shoots a .36 caliber within a plastic wad/tube. It seems it would be easy to make a Breneke type slug by attaching a long base wad to a solid .357 bullet possibly a semi wad cutter in the 158-200 gr range. A second thought was if a sabot could be made to spin in a smooth bore barrel. Looking at cylinder bore for both slugs. Anyone working with the 410 or any ideas? A 3" shell carries 5 #000 buckshot which is why I am interested.
