I just got back from testing a second round of handloads in my .308 Axis. Good new is that I found at least one excellent load with every powder I tried (I'm using Hornady 150 SST bullets). None of my loads are max loads, according to my Hornady manual. The closest I came was 1/2 a grain low with H335. So the problem is that the bolt is sticking, as if I'm over max pressure. Since every gun is different, I could accept that mine likes to be 1 or more grains light of max, but I'm getting this with midrange loads for 748, 8082XBR and 335. 760 did the same thing when I tried Sierra 150 FN (30-30 bullets). There are no flattened primers, split cases or other pressure signs I can measure. I've cleaned the bolt and the rifle, but I'm still at a loss. Any help or suggestions?
