Rantus interruptus again. Ingwe, no I haven't had any pressure problems with H335. Usually I work up loads in warm weather and hunt in cold weather, so pressure problems haven't been a problem. My H335 load for the 40 grainer is about a half grain shy of max. The BL(C)-2 loads are a bit less warm. When it was hard to find H335, I found plenty of the other, and decided to see if it would shoot as well as the H335. It shot just fine, and when I run out of H335, I might just use up the BL(C)-2 before I get more H335.
