My 22-250 is finally showing some promise. I have worked with several bullets and really hoped the 35 grain BTLF would shoot but an inch was the best I could get. I had some of the Sierra 50 grain Varminter bullets around from working with my .22 Hornet and decided to load them up. Yesterday I went to the range and shot a few different bullets and the Varminter was the most consistent. Today I loaded up a bunch more and shot several groups with each powder charge. 5 five shot groups went .254" to .310".
Load info:
Win brass
Rem 9 1/2
36.5 grains AA 4064 - above Sierra max, in the middle of Accurate data - no pressure signs
Sierra 50 grain Varminter #1330
2.395" COAL
MV - 3721 FPS, ES 4 SD 9.
AA 4064 is basically a short cut version of IMR 4064, with about 2% less energy than an equivalent weight of IMR 4064 so it has excellent case fill.
