[QUOTE="rufous, post: 211268, member: 122"] I have had good results with RL22 in this barrel and the previous barrel but when using 180 grain bullets. I just figured I would use the slower burning powders for the heavier 200 grain bullet, thinking that I could possibly get a bit more velocity at a lower pressure. Is that not proper thinking? Is there something wrong with using RL25 with the 200 grain bullets? By the way this rifle is my pack up the mountains big game rifle. As such it has a sporter style Rimrock synthetic stock and a Leupold VX3 3.5-10 scope with the Boone and Crocket reticle. It weighs 9.3#. It is not a heavy bench gun. I can quite consistently get sub 2" groups (3 shot groups) at 250 yards which is the distance at which I zero my main crosshair. The load mentioned earlier of using Ramshot Magnum to get an average velocity of 2960 gave me a 1.58" and a 1.41" group at 250 yards. That is about all I can do with this gun. I have occasionally gotten smaller groups but this is pretty standard. Still I would be happy to reduce my extreme velocity spread. I very seriously doubt that I would take a shot beyond 600 yards but would feel more confident if the high and low velocities were closer to the average. I have never annealed a case neck. Can someone recommend a product for me to use? I think I remember hearing that Hornady is making one that works pretty simply. Thanks, Brian. [/QUOTE]
