I have been shooting my 50-70 with Trailboss and got a bullet stuck in the bore. I was using light load with 650g pulled BMG bullets. H322 has worked pretty well, but I want to reduce recoil some. These bullets take up a lot of cartridge space. I want to be carefull about pressure as this is in a pistol barrel. Slow and accurate is what I am looking for. Any suggestions on starting loads? Thanks!

Check Accurate Arms web site and the Lyman Cast bullet Handbook. they have data for lighter bullets but not the BMG bullet.
