[QUOTE="JAYgs8163, post: 2271932, member: 37460"] Well, I have experienced the large temp swing pressure spike and I know others that have. It may have something to do with load development as I stated in my earlier post. I developed my load in 50-60 degree weather in my 6.5 Creed and in my 65 PRC and settled at about .3-.5 grains under where I experienced max pressure. Shot 150-200 rounds with no issues in the creed last fall and spring and this past summer shot it around 90 degree temps and had very bad ejector marks and hard bolt lift from the same batch of loads I had shot in 50-60 degrees. I unloaded 10 of them out of the 50 I had left and backed down a full grain and no more pressure at 90 degree temps. I went back out last week and shot the original full load early in the morning when in the mid-high 60’s and no more pressure, shot early afternoon in the 90s and pressure again. I tend to run my loads right on the edge of max pressure but I won’t with RL26 anymore. No “BS” here just the facts of my experiences. Same thing experienced with my 65 PRC. If I run RL26 I will run it 1-2 grains under my max pressure signs or develop the load when it’s hot out already. I really like the powder but I have had some issues with it in large temp swings. Glad you are having such good luck with it. [/QUOTE]
