I went to the range today and got good results from 250 grain Missouri bullets in my rifle with 8.5 grains of Unique. I used some 250 laser cast with 6.3 grains of Titegroup with shotgun patterns. I see no pressure signs and am sure this is asked a million times. How strong is the big boy. Ruger only states Marlin and Thompson center with rifles. I chrono graphed 1112 fps on average with the Missouri and Unique. Titegroup loads were so erratic I didn't bother. I would like to try 9.5 to 10 grains for a little faster. Not wanting excessive speed but want more than I'm getting. Any suggestions???
