OK so I just got back from the range as you can tell from my last thread, I have been trying very very hard to get my M70 308 FTW to group well with 165s like it does with 150s since I have never used 150s for hunting (not in 30 cal anyway), well today I tried something off the cuff and loaded 180gr SGK over W748 just to see, WOW a .515" group with the first three shots! My jaw about hit the floor! So it shoots 1/2" with 150s, 1/2" with 180s but 1.5" is the best I can do with 165s?!? I asked the reloading guru in the shop and he has never seen anything like that either, had the 180s not grouped I could have chalked it up to the slow twist but this one has me scratching my head, and yes I have tried just about every 165gr bullet/powder combo you could imagine within reason, RL15, Varget, H380, Big Game, 748, BL-C(2), Speers, Sierras, Hornadys, Noslers.....etc, anyone have any ideas?
