I've used H-335 in both .223 and 30-3- with good results. I hunt PA groundhogs and the Hornady V-Max over H-335 and a CCI primer hold under 1/2" @ 100 yards consistnatly. It works well with Sierra Blitzkings (40, 50 and 55 grain). My '94 Winchester likes this powder under 170 gr Sierra FN. Never could get it to work with the Hornady Flex tip (but then, neither did anything else in this rifle!) PM me if you want the exact loads - they're not max BUT I only claim they're safe in MY rifles loaded MY way.
