WRT the Federal 10ga hull and the paper basewad coming loose. I think that worry is akin to worrying about shooting nitro powder loads in composite barrels, ie nothing to worry to about. The guys who reload the high pressure fast steel in 3.5" hulls are not worried about it, I am with them. FWIW hulls with paper/composite base wads will have lower pressures than hulls with plastic base wads.
I agree with Paul loading for shotguns does not require the same precision as metallic cartridge.
