[QUOTE="Wedgy, post: 2489434, member: 64108"] [I]Very nice ! I have run several 26" barrels just under 3,000 fps at mag length ~2.7" SAAMI chamber with the Berger 230 OTM with ~89.9 grains of Retumbo so you should get an extra 100 fps with your long barrel. I think starting at 85 is good, you can go up a grain at a time as it is a small percentage 1.2% of the load until you hit pressure. Shoot a ladder at no less than 600 yards, these big bullets need range to show a node. What type of hunting/shooting are you doing, doesn't seem to be a pack gun or you are young and strong. The only thing I may advise is to go with a 9 twist barrel next time, bullets are only getting bigger and need more twist.[/I] [/QUOTE]
