I recently finished a .260 build. Aero precision upper/lower, 20in krieger barrel, slr adjustable gas block, and aero precision bcg(high pressure). I am getting pressure signs on my case head, even on the low end of my load development. Cases are not beat up, primers are great, no extractor marks. Just a lot of flow around my ejector, not on every case. I would say 50%. I worked from 42-43.5 grains of h4350. I tried 140 class and 130 class bullets. All with similar results. If I close the gas block no pressure signs at all. Even worked up a little higher 43.8. Would a heavy buffer slow my unlock down enough to help with brass flow?
