Moosehunter, I am using Federal cases and Federal 215 match primers. I am using H1000 and 77.0 grains is giving 2870 fps. This is a hot load. Do not try it without working up to it. It is likely well over SAAMI max. I was shooting 76.5 grains and got some great groups but was also getting some shots that were well out. I did not think I was flinching but with a 9.3# rifle the recoil was pushing me around a fair bit. So I had Darrell Holland install one of his muzzle brakes
. The recoil reduction is amazing. This is my climb the mountains big game rifle so it has a fairly narrow sporter stock. With the brake it wanted 0.5 grains more powder (I have not tried 77.5 and it may be more accurate but at 77 I am happy). I shot 3 groups of 3 shots each at 100 yards with the 77.0 grain load (bullet is 0.010" off the lands). The largest group was 0.8" and the smallest was 0.63" for an average of 0.75". If I had shot all 9 at the same spot I would have had a 1" group. Then I fired 4 shots at 300 yards and got a 2.1" group. This is not that great for many of you but for me I am quite happy, especially considering that it is a light rifle with skinny stock and max magnification is 9x. I cannot imagine taking a shot at an animal beyond about 600 yards since I will not be hunting from a bench, but rather on foot with just a sling and bipod. So the accuracy is plenty for the type of hunting I do. Rufous.
