Went back out and refired some of the loads that I shot yesterday.This time I used once fired brass,I backed off from 69 gr to 68.5 gr as my top load, here are todays results.
Barnes 168 gr xlc
67.5 gr 3058
68 gr 3115
68.5 gr 3152
None of the cases expanded more than .0003
When I get a chance and the weather clears up, I am going to fire a five shot string for average, I have a load built up with 70 gr of IMR 4831 that averages 3115, looks like RL 17 does add a little speed to the 300 wsm. I also fired a five shot string using 61.5 gr of RL 17 and the 200 gr Barnes X bullet, I got an average of 2748 with that load. I built up a load about two months ago consisting of 74 gr of Ramshot magnum, that load averaged 2736 and shoots one inch groups, I don't know if RL 17 can match it for accuracy.
