[QUOTE="J E Custom, post: 135599, member: 2736"] TMR The 7-08x40 that I had was built for 140 to 160 gr bullets with a 1 in 9 twist 22" hunter bench rest tapered barrel Fire forming was not a problem and powder capacity was about 8 grs more than the 7/08 allowing slower powder to be used. Best loads were, 140gr partition with 55 gr H4350 @3155 vel 160gr partition with 56 gr H4831 @3105 vel Also it liked H414 with 145gr bullets. With the new 7 WSM & 7 SAUM powder capacity has increased to about 70 grs so the advantage of case capacity and newer slow burning powder will improve velocitys with larger bullets and still work in a short action. NOTE these loads were max so start low and work up I hope this helps [img]/ubbthreads/images/graemlins/cool.gif[/img] J E CUSTOM [/QUOTE]
