162 AMAX in 7-08, what powder? - 07/14/12
I am loading for a Sako A7 22"brrl. The mag will feed a COL of 2.9"
I am looking for 2700fps with low SDs and small groups.
Today I tried RL17 up to the Hornady book max of 46 grains and hit 2780. Accuracy was un-satisfying and I was seeing early signs of pressure. I am not liking this powder in this application. I shot powder from the same canister earlier in the year when it was cooler and saw notably lower velocity and pressure.
Here are the slower, applicable powders I am looking at next; N550, Ramshot Hunter, H4350, RL19, Win 760.
Any experience with any of these combinations? Any other recommendations?
