[QUOTE="Ryder12, post: 3013527, member: 116009"] I spent years trying to get a 22-250 to run 55 gr bullets that should have worked. Even in this thread someone said they shot good groups with a 14 twist barrel, I measured it and 14 twist. I dropped down to 52 gr and bingo one hole. I suggest you determine what your twist is manually and drop down to a 52,53,55 gr. Some pictures of groups might help in determining you issue. 1. Use something other powders that work well in a 22-250. H414, IMR4064, W746, 4895 2. Make some sand bags and shoot off a concrete bench. If no bench then go prone with the bags. 3. ALL scopes fail. Especially Vortex, Weaver, Leupold and Chinese scopes. 4. Check the chassis for rubbing if there is some rubbing, bed the action. Reduce all loads by 10% and work up. Sierra 5th Ed "Accuracy" in their test barrel 52gr 34.1 gr IMR 4064 55gr 35.2 gr IMR 4064 My load and "most accurate" was in Ken Waters' Pet Loads ( a bit out dated but worth the money) 52-53gr 42 gr H414 Seek out a competitive shooter who has been reloading for at least a decade. Get his advise, in person. My advise is to sell the Ruger and buy a Tikka. You can buy prefit barrels for the Tikka. CTR would be my pick in 6.5 CR and when it's burned out prefit 6mm CR. So to recap, I had a 22-250 with a 14" twist that did not shoot 55 gr bullets when all the experts including SIERRA said it should. I finally listen to another shooter (after 2-3 yrs of fighting it) and shot very, very good groups with 52 gr bullets. 3 grs isn't much. Drop the bullet weight and get some better powder. [/QUOTE]
