I don't think the twist will change much . you are one inch shorter bbl so you are going to run a little slower velocity . I just ran a 22 in bbl with the 45.5 RL17 , everything else the same as before . the 23" bbl = 2913 fps . the 22 " bbl 2886 fps . Jim
edit . the max load , pressure will be the same . Jim
