The twist interests me, I have a system One which has a 1-38 twist it shoots 230gr 45 bullets real well also will do a good job with the 250gr but when it shot PRB all the way up to 90 gr of P and keep as good a group as the sabot bullets it got me interested, I wish they made a Triumph in a 54 with a 1-80 twist, if they did that would be my hunting gun.
