I used H335 in a .30-30 in the 90s. It was my farm gun...rode beside me in the pickup while baling, fencing, etc. I was using fairly mild loads, but noticed a sharper report and a little more recoil if I let a round off on a hot afternoon when the rifle and ammo were nice and warm. I now use IMR 8208 and it seems better behaved on hot afternoons.
