[QUOTE="mhamlin, post: 1184730, member: 68822"] Crockett, I have the same rifle, same caliber with a custom muzzle brake. I tried the 215's and the 230's and got the best precision with the 215's. Retumbo, US869, H50BMG, and other slow burning powders produced more speed, but H1000 produced the most consistent load for my rifle using 89.5 grains of H1000 (well below max load)+ CCI 250 primers = 2954fps. I was able to get over 3200 fps with the others, but groups went from sub-half MOA to scatter gun performance. Don't waste your barrel chasing fps like I did. Retumbo is a favorite for this combo and may shoot well in your rig, so you should give it a try. Seat your bullets to mag length and fine tune your powder charge to your best groups and don't worry too much if your 100 yard groups don't meet forum standards; my gun didn't shoot its best until we got well past 300 yards. Plan on spending more for your scope, than you did for the rifle...put the best scope on it that you can afford and go have a blast! -Mike [/QUOTE]
