[QUOTE="longrangehunterII, post: 766501, member: 61185"] Wow, I must say that round turned out great with some real potential! So this question is open to anyone with some experience to which powder might work best for pure accuracy without too much trial and error in a 6.5/300 WSM, since barrel life could be limited. My current load is 65.0 grains of Retumbo behind a Sierra 140 gr. GK @ 2.400" ogive length. It shoots 3/8" groups @ 100 yards, but only at 2990 fps average 20' from the muzzle w/ a 24.5" barrel. I was hoping this would keep it shooting great for a longer period of time? I tired IMR 7828, 7828 SSC and H4831 during barrel break in with little luck. I'd like more speed but I don't want to give up anything in the accuracy department. I have a box of 140 gr. Matchkings I'm thinking of toying with, but I hate thinking of all the load development it might take to produce another better round. I have enough magazine room that the 140 gr. Matchking's will seat with the Boat tail taper right at the neck/shoulder juncture in the case. So my hope is that it should shoot well if I can find the right powder. So any suggestions would be greatly appreciated. Thanks [/QUOTE]
