    Thanks, cabezaverde. I've been reloading for around 45 years...pistol, rifle and shotshell. I've read a lot about reloading in that time, and have done a lot of reloading and shooting, but like I said "my memory is a little fuzzy" ... I blame it on my age (70). I tried to give a little history on the H320 powder as I remember it, and I avoid giving load data to people in online forums (but I don't know any load data about H320 because I never had any of that powder.)

    Thanks to all of you. Loaderdewd, good information and understanding not putting load data out (although I understand you don't have for this).
    I have what I need to get started with it. I have worked up surplus powders in the past, never knowing exactly what they were. I just gave them my own name to keep records. Dan

    Well, I started with 30gr of H320 in a 7.62 nato brass behind a jacketed 150 bullet. In a FR8 mauser. I yanked on the trigger with a string, being cautious. As I expected, no signs of pressure and is likely a very mild load. Good. I can work up from here. When I see signs of pressure, I'll chronograph and I should be able to nail down the burn rate.
    The only reason I used jacketed bullets to work up with, is lots of data available to compare with.

    Good job Dan. I bet that is mild, H322 starting load minus 20% is approximately what you got there. You will achieve about 2650 fps with safe pressure and your 150 gr bullet, that's my prediction . Keep us posted
    Hell, I was there!

    Thank you Sir. That is pretty much how I determined my starting load. The goal is not necessarily to work up a load with 150gr jacketed bullet, but doing so would be great for hunting. I hope to use this powder for a variety of cartridges, from 223/jacketed to whatever, with cast bullets. It would be nice to use with 444 and 45-70 cast. Especially 30-30 with cast bullets on silhouettes.

    I think you will be able to do exactly what you want from this powder in every cartridge you mention. Ten pounds of this was a sweet find!

    With loads of 30-34 grains, 150 sp, they were mild, low recoil, and no signs of pressure. GREAT. I can proceed to go up until I see signs of moderate pressure. Something to note, one load shot a 5 shot little round group, that could be covered with a quarter. This is at 50 yards, with a FR8, iron sights. Heck, I can't see that good, so there must have been some luck in there too. The FR8 never ceases to please.
    The recoil felt like a reduced power load. Yay!

    Sounds like that mauser will shoot. I miss the hey day of cheap surplus powders and cheap surplus mausers. I just recently bought one of those cheap TC compass in 308, it is being fed WC846 since I have some left, when it's gone will start on the T2208, oh my an era gone.
