[QUOTE="liltank, post: 382705, member: 13275"] Don't give up quite yet on the 250's. I would play with length a little. Take it to the lands, .005" off the lands. You already know .010" doesn't work, so try .015, and .020" off. This may give you the results you are looking for. One thing that I did that drove me up a wall is trying to pick different powders and bullets to work. I decided to just pick a known powder that worked in the caliber, and the bullet I wanted to use. Viola... found a recipe that works. 61.5grns H4350 and a 208 A-max on the lands. The H4350 is a known powder to work well in the WSM's and the 208 is the bullet I wanted to use. Not quite the speed I was looking for, but it is accurate as far as I am concerned. Rolled a groundhog at 975yrds with it. Hain't to shabby!! Tank [/QUOTE]
