Recently joined this forum. Have a question concerning my T/C .58 Big Bore. Has single trigger and just a 4-digit serial #. Is this an early Renegade, or just a regular .58 Big Bore? Would also like to know the twist rate. Shoots 1" group with 282 gr, .575 RB .010 patch and 80 gr 2f powder @30ygs. Any info would be greatly appreciated.
