[QUOTE="Shooter264, post: 1263829, member: 23746"] I've build them off 8 twist and 8.5 and there is no discernible difference in velocity between the two, never bought into the 8.7 as being optimal because the difference between that and 8.5 would be minimal. I've had 7 6.5 saums and they have all ran 3080-3090 with a 140 and 24" bbl and 61 H1000. My 23" 8 twist barrel runs 3070 which is a little faster than I anticipated. Use what's handy, it'll work just fine I've used a plethora of different bbls as well. mullerworks, Brux, Bartlein, and proof research. Ironically my fastest was an 8 twist mullerworks at 3090 and brass life was great. No problem getting 7-8 loads on Norma brass. I believe GAP has now switched to chambering all their rifles on Bartlein 8.2 twist bbls [/QUOTE]
