You will not want a 1-48 twist to shoot long heavy conicals. A GM-LRH drop in will work for you if you can find one...
This one of mine...
And this the other...
Both barrels a 15/16" across the flats and dropped into a 1" barrel channel of the Renegade - works great.
These things shoot the .503-460 grain Bull Shop Conical - GREAT
