.452" pure lead or close to pure will be .001" over land bore. Each land will engrave .0005", and keep your bullet on the powder. A .030"-.060" thick by .462"ish diameter vegetable fiber gasket wad would be best in this application, between powder and bullet. I prefer the. 060" thick wad in my 3 different brand .451's with 1:20 twist. 70 to 90 volumetric grains of powder should do it for you. Start low and work up in 5 grain intervals, then fine tune from there.

If you want to shoot a squib load to foul your bore before hunting our target shooting, you could get away with a .451" diameter bullet.

I prefer pure lead at .001" over land diameter, with the veggie wad.
