Anyone have data on powder for temperature swings? Fps loss or gain in different temps?
I have noticed my loads with some of the Reloader powders (19, 22 & 25) that are accurate at hunting temps (20F-60F) are 100 fps or more faster when I shoot the same loads in the summer time heat (95F-110F). Anxious to see what the new RL 23 and 26 will do.
Can not tell you about temp sensitivity but ES is absolutely AMAZING and velocity is as good as it gets in my 6.5 Sherman and 6.5 Sherman Shortmag with RL26. I had single digit ES consistently, and some three and four shot strings were only 2-3' and one string only 1'. I have never seen es this low. No, it was not the chronograph! I was using a mag speed and tried another powder at the same time which gave me spreads of 40'.......Rich
