I am looking at .50 cal sidelocks that aren't the length of a pine tree nor the weight of a boulder for hunting with, but it seems all I can find are 1:48" twists, which I'm told really won't keep a good grouping. The only rifle I have found was Lyman's Great Plains Hunter with a 32" barrel, 50" OAL, and 9 lbs. It's nearly as big as I am!

What kind of groupings would you expect with light/heavy 44/45 bullets in sabots or 50 cal bullets at 100 yds with a fair rest? I'm thinking 100 yd 0 with 125 yds as a max range.

Anyone use SST, FTX, FPB's and notice much better groupings? It's what I was considering when, after punching in the numbers on a ballistics calculator, I thought 175 yds ought to be doable.
