Have you noticed that if the bullet is longer in legth, you can speed it up? According to the program I have the length has more to do with stabilization than does weight.
Thats part of why I do not see a fast twist Knight doing well. In todays world of magnum loads and long range shooting, I don't see the everyday average guy willing to give up the speed, to shoot a fast twist.
Which again would be Knight trying to supply a very small, niche group.
This is exactly why i question this move knight is making in regard to changing the .45 cal twist. the 1:28 & 1:30 twists shoot the 40 cal bullet offerings excellent, with the exception of the 200 gr .40 Lehigh which needs to be pushed to 2300 fps or more in these twists due to it's length being to long.changing to a twist that has a bad reputation deserved or not, for one brass bullet and heavy conicals to me is madness.i have seen tons of testing on bullets for the .45 cal 1:28 & 1:30 and PR bullets has done major testing on the .45 cal 1:20, which doc white shot a 350 gr saboted bullet from accurately..
staying with the 1:30 and developing jacketed .40 cal bullets in the .220-.260 range makes a lot more sense and would be a hell of a lot less risky.Knight can't afford two red headed step children ( .52 & 1:20 .45)
