jh45gun , I think I just found another good load for my Rolling block today. I tried starting load of 31.5 grs reloader 7 behind a 405 gr. rem. bullet, OAL is 2.700. That's about .035 off rifling. I got that load off the paper that came with my lee loading dies. First try was a 4 shot group that measured 3/4" high,and 1" wide at 100 yds. I also have a tang sight and a lyman 37A front globe. Of coarse this was shot off of a bench, I probably couldn't hid a peck bucket off hand.
