    That looks like the same powder I pulled from some Egyptian 8mm ammo.

    I've seen a lot of that square flake powder. I recycle the scrap brass from my club's range and there are usually a number of milsurp duds in the brass bucket. I disassemble them before selling the brass to the scrap yard and that square flake is pretty common.

    A WAG but I'm guessing that it is rolled out into thin sheets not unlike cookie dough then die cut into the squares before final drying.

    My understanding is that gunpowder is processed wet during mixing, forming/extruding.

    As a paste I suspect it could be rolled fairly easily. Not much different than pasta.

    Just a little more BOOM! When done.

    Doubt if it was any one specific powder, I've seen variation in color over the years.

    The standard German service powder for the 7'9x57mm (Nz. Gew. Bl. P.) measured: 2mmx2mmx.045mm. It was used in all ground gun loading's for all projectile types. Many European military 7'9x57mm cartridges are also loaded with a similar sized propellant. They was a HV propellant utilized in special 7'9x57mm aircraft ammunition, but it was tubular not flake.

    I have a bunch of very old 8x57, 1929, 1930's, 1940's stuff. All are cupro-nickel, 150 gr +/- and have flake powder of green grey appearance similar to what is shown.

    I too have seen it in Mil-Surp German ammo. Kept some for a while to show around to friends then used it for fertilizer.

    8mm turk is loaded with the same stuff. Hotchkiss Flake powder or something like that. I weighed and averaged the loadings and reloaded about 15 % less.

    I did the same with several hundred Turk 8mm rounds. I averaged out the powder load, made a label showing this as the max load with the original bullet weight and stored it in a plastic coffee tub with a snap on lid.

    Couldn’t see throwing it away!

    I've always liked 4320 for the 8mm.

    I dont think you'll find any. Any mid range powder would work great, like 4320 above which I started to standardize on for all like-cartridges but they just discontinued it.

    IMR 4064 works very well in the 8x57 cartridge. That's the powder I use in my 8mm-06 Ackley Imp. as well.
    If a 41 won't stop it, I wouldn't bet my life on a 44.

    It's Nobel powder. As mentioned commonly loaded in metric cartridges for many, many years. No idea where to get it or even if still commercially available. I have used it as "pull down" from many different kinds of cartridges over the years. Burning rate of different lots has always been really close to 3031 and 4895.

    Looks like some pull down powder from some 1950's Turkish 8mm cartridges I bought some years ago. I reloaded the powder, used new primers and R-P cases as bullets with the bullets. I weighed each powder charge as I pulled it down. I took the total weight of powder and divided the number of cases into the total powder weight and cut the charge by 1 grain of powder. Turned out to be some of the most accurate military type 8mm ammo I ever shot thru that old Turk. Standard deviation on the handfull of cases I measured was very low. I was also very impressed with the very small variance of the weights of the individual charges of powder. james

    Was just gifted a 1/3 lb. of Alcan 8, looks a lot like your 8mm powder. Can said it was, if I can remember correctly, manufactured by Bofors.

    Attachment 270484

    Going to try it in 45 ACP, found a load for it in 45 Autorim, found other references claiming to use starting loads for Blue Dot, going to check on those loads and then load up a couple to shoot.

    Around a corner with my safety glasses on and my legs crossed................

    And tried 4 this morning, fired, cycled the action and the empties made at least 2 1/2" above the gun before rolling off my wrist. Certainly not going to have to chase brass. May add another 1/4 grain to make it cycle with a little more authority.

    Current load:
    WLP
    7.0 grains of AL-8
    Ideal 452460, 218 grains with two coats of Ben's Liquid Lube. Current references say this is a 200 grain boolit. Not this 4 cavity mold.

    Going to up the load to 7.25 grains and try it again.

    Not bad for a 50 year old powder.

    4064 has proven to be the go to powder for my 8mm's also.
