[QUOTE="Jumpalot, post: 801514, member: 4867"] I'm running a 26" barrel and I carefully worked up to 67 grains of H4831 and get 3080 fps. I got all the way up to 69 grains before seeing pressure (light ejector mark). I also fired over a chronograph to watch velocities as I worked up. I saw a consistent increase of 40-50 fps for every 1 grain increase in powder charge. But there was only a 10 fps increase from 67 to 68 grains. Also, 67 grains showed my best ES. Long story short, carefully work up a load. I don't think you'll get to 3000 fps with a 22" barrel though. [/QUOTE]
