I have several 8's and a 12.
33 cfe223 and 55 Nosler bts at 2.280 with CCI 450's both shoot 5 shots well under an inch at 100 out of the 12 twist woa as well as the Wilson combat 8 twist. If I recall the Liberty 8 twist shoots it well too. The 8 twist bhw is a bit finicky but shoot very well with 53 VMAX and I think 33.2 grains of cfe223. I know of 2 other woa 12 twist and a predator contour 20" 8 twist woa that also is very accurate with the same 33 cfe 55 bt load.
