i have the fast twist long range hunter in 50cal and the slow twist 54cal on my renegades and i love them both. can't tell ya much on the r/b question though as i shoot lee r.e.a.l. bullets in my slow twist guns. nothin' against'em except hard to load after first shot just never been a big roundball fan. anyway, both barrels are as or more accurate than i am. for what it's worth and luck friend, bubba.
