Took my GM 22 1x28 put it on My Lyman Deerstalker. I shoot 80 gr of 2 f black with a home cast 300 gr 430 bullet shoots very well. I also shoot 70 gr 2 f with a 400 gr 458 resized to 452. It is basically a 45/70 carbine shooting at 50 yards of bench 3 inch group w/ iron sights. The Lyman came with a 1x48 54 cal.
