[QUOTE="DaveB, post: 3703921, member: 5958"] My Browning Medallion 22-250 has the standard 1 in 14 twist which means I am very glad to be able to stabilize 60 grain partitions. I fell for the advertising and bought some Superformance powder. Sure enough, I am getting nearly 200 FPS more with this powder and although it took some doing, the groups are tighter. Only rifle I own that got more accurate as I moved the bullet away from the lands to a final OAL of 2.470 to 2.475. I am 10-10 measuring 43 grains of Superformance into R-P cases on top of Fed 210M Primers. Interesting. I have the 43 grain ladder circled and wrote WOW next to it. It took quite a few ladders to get it, but the final result was kinda nice. [img][IMG]http://i1118.photobucket.com/albums/k610/12semi/Dadstargets075.jpg[/img][/img] Couple of points here: (A) I was getting tight nice repeatable groups using RL15. (B) Superformance powder smells like rotten eggs and leaves cobwebs in your barrel. Really the dirtiest powder I have EVER used. I use Gunslick Foam to clean and if you can do it outside, so much the better. (C) Going back to RL15 (I have 4+ pounds) [/QUOTE]
