Knights own 45cal target rifle model DE658B was a 1-18 twist 28" barrel Extreme. It won for several years if not all years between 2001-2006? Its in the Knight 2006 catalog.
Nearly all the of the Savage and Remington replacement SML barrels PacNor/Krieger/McGowen/Brux/ect are from 1-18 to 1-22 twist and shoot 40-200gr bullets in sabots with amazing accuracy even at 300 yards or beyond. We are talking about a saboted bullet moving upto 3000fps and 35k psi or more.
These are highend barrels with a good history of proven excellent accuracy. Add in the sabotless applications also and the sky is the limit. Busta was shooting the 250gr SST sabotless/BH209 in a 1-20 at speeds (2300fps) exceeding most 50cals and doing it VERY accurately. Sabotless isn't for everyone but its not that hard with 1-3 sizing dies and 2 files.
IMO a fast twist 45 has serious potential to get costs down with conicals or sabotless without sacrificing good sabot accuracy too. Just don't expect a 155gr bullet to shoot accurately at 2500fps with 3 Pyro pellets. Personally i want a custom 1-24 twist 45cal or a gain twist barrel ending in 1-18 but those are SUPER expensive to make. Just the straight 1-24 twist is going to cost me an additional $150 from Pacnor vs their standard 1-22 twist.
