    So you are better off with a slower twist in this cartridge for more velocity? How are they with a fast twist barrel and 105gr low drag pills?

    Personally I have grown to like the slower twist. Ive built several others now with 1-10" twists and they show a drop in velocity with the same loads even with longer barrels than my 1-14" twist. Mine absolutely loves the 75gr HPs so I am happy running those exclusively.
    @Mathias has built a 1-8" 6x45 and has some pics and info on it on page 8 of this thread, maybe he can comment on shooting 90gr+?
    I would guess mag length would be the biggest drawback when loading the 100gr- 105gr bullets. if you cant load them long you are taking up a good chunk of powder space. In most of the repeater .223 actions Ive checked, you are limited to a max 58-59mm OAL
