My 1 in 8" 223 AI and 22-6mm both shoot 40 grain Ballistic Tips quite well. No reason to go with the slow twist. This isn't 1920. Modern bullets stay together when twisted to high RPM.
Hrmm, maybe I should try some 120 VMAX's in my 1-8.75" 7x57. So far the only thing I have tried that light in it is the Barnes TTSX. They shot pretty good running them slow, but I never did pursue it. I didn't think I would be able to hold a more lightly constructed bullet together, and Barnes are kinda expensive for target practice.
