I have a 20 gauge Remington 870 with a rifled barrel and scope, that I use for deer hunting here in southern Minnesota. Till this year my choice of ammo has been Remington AccuTip 2 3/4" slugs. It is a really accurate load in my gun. Of coarse this year, with all the goings on in this country, if you can find these cartridges, they are very expensive. I decided to roll my own and have been looking at information that talks about using a 58 cal. muzzleloader boolit, some nitro cards and a plastic wad. I think it's recommended to load into 3" casings to have the room to crimp. Has anyone been loading anything like this? My boolit is a 315gr hollow base minni type. I have some Winchester AA wads but I'm not sure if they can be used or what would be the wad to use. I'm trying to get to where I don't have to rely on availability and over pricing, to be able to get out and shoot or hunt.
