im wanting to try H335 in a 308 loading just wondering if anyone else has used it and what kind of results have you got. Most of all im curious how tempature sensitive it is and should I use a magnum primer with it with my BL-C(2) loads ive found to work best with magnum primers or is it kinda a rule of thumb to use mag primers with ball powder?

H335 is a good powder. I don't know how temperature sensitive it might be, but it's been on the market for ages! So it is NOT one of the new, temperature-stable powder formulations. I have never used it in the .308, where I found that H380 really shines! But I DO use it in the 7.62X39mm - 28.5 grains of it with the Speer .311"180-grain round-nose (2000 FPS), and 31.5 grains of it with the Sierra 150-grain .308" flatbase spitzer (2300 FPS) from an 18.5" CZ carbine barrel. Needless to say, these are HOT loads!

It is a rule of thumb to use magnum primers with ball powders, as they are supposedly harder to ignite. Some people used to get hangfires with H450 in large cases when using standard primers. I have always used standard primers in all cases except the .416 Rigby, and have never had any problems when using Federal 210 or CCI LR primers with ball powders in standard size cases.

wow!! 180 grainer from a 7.62x39mm thats gotta be a good whitetail load. where on earth did you find load data for that load. with the 150 grain load thats some awesome shooting would have never expected that kind of accuracy from the stubby 7.62x39. thanks for the post

I use h335 in my 45-70 and dont use magnum primers, do love the way it meters from a measure. I mostly use Varget and Benchmark in my 308!

I don't exactly recall where I found that 180-grain load, but it only works (for me) with a round-nose bullet, because the180 spitzers are too long to seat the bullet properly with that much powder.They end up too long to work through a magazine. For a rifle with such a massive receiver and bolt assembly, the SKS has a magazine that is on the short side. Of course, it is madefor the military load, which is quite short. I used it originally in an SKS, where it works OK, but now I do MOST of my 7.62X39mm shooting with a CZ 527 carbine. The CZ is a lot more accurate, and much easier to carry around and handle than the clunky old SKS!
