I have been away for awhile, have been shooting my 1896 carbine in local military matches. Good accuracy with 9.7 grains Unique and 165 grain cowboy cast bullet, very happy with it. Question is: would like to develop load for 30 40 Krag Ruger No. 3, but above load doesn’t work! Where do I start? Would of loved to have same load for both, guess won’t happen. 1896 does inch and under groups at 50 yards.
