    Second!

    Years ago when Turkish was cheap (and of suspect quality) I bought a case of 3400 or so for about 4 cents a round. Tore it all down and reloaded it w 10% less powder in 500 round lots in 8mm Portugese boxer brass for my MG34. Gun chattered with glee and I didn't have to sweat an immediate cleaning session after shooting! Wish I had more!

    I have done the same over the years w surplus Bulgarian, Czech, Egyptian, Romanian and Yugo that were mis feeds, mis fires or lots that had too high an incidence of bad primers or hang fires.

    Ian McCollum has several videos on Egyptian, Turk, Ethiopian, etc., varieties of surplus 8mm (and other chambering) on his “Forgotten Weapons” channel on youtube, and actually illustrates the components.

    I haven't loaded 8mm in years, but when I did I always used IMR4350.

    In the 8 X 57....well, in all the 57mm cases based on the 8 X 57, I've had good results with both 4895's and IMR-4064. They all worked equally well in my 8 X 65R Brenneke double and I'm curious to see how they do in my Merkel, O/U double in 8 X 60R Magnum. It might need a slightly slower powder.

    I have several hundred rounds of Egyptian 8MM Mauser ammo I bought several years ago. I started trying to use it recently and found all the primers had failed. I pulled some rounds and checked the powder. I started using it in my '219 Zipper and after several loads tried the powder seems to be very similar to 3031. 24 grains in my .219 gave excellent results with no sings of excess pressure and was a strong load. I have no idea what the fps or pressure was but I wouldn't increase the lode more than 24 grains. I am pleased with the performance of the powder plus I have many 8MM FMJ bullets to sell in this hard to get bullet time. Also brass cases to recycle. It is a pain to pull so many bullets but the powder is defiantly a very good benefit. I will sell the bullets very cheap on the for sale forum here.

    I have used 4895 mostly in the 8mm but did try some 4064 with 170 and 175 grain bullets but eventually went back to the 4895 and it is my standard now. james

    The only powder I ever used in 8mm Mauser was IMR 4064 and it did everything I wanted it to do.

    4320 was a good one for a 180 bullet. Alas, it is no longer made.

    I have been using pull down powder from some Egyptian 8mm that the primers went bad to where there were no firing at all. I have been using 23 grains with a 55 grain spire point in my 219 Zipper and it is accurate and clean. 23 grains may be a little hot for my Falling Block Works K frame as far as a case tends to stick some and extraction is slightly difficult at times. I think I will drop the charge to 22.5. This square flake powder seems to be near to 4198 in performance. I will check the velocity in a couple of weeks.

    From the data I have the standard thickness was 0.050mm. But they varied it between 0.045mm to 0.055mm depending on the linear burn rate of the input product. This was done in 2750 pound quantities.

    What I don't know is if the various thickness’s where mixed together when they blended the 22,000 pounds of powder together to make up the single lot of powder for loading.

    FWIW. Each batch of powder used for input for a given size was blended from 10 different individual batches of NC. So by the time the powder was loaded it was a blend from 80 different batches of the raw input.

    You can get a high grade and tight tolerance raw nitrocellulose for $16.00 a pound currently. Just have to process it into the desired powder.

    For a bit lower grade the price is around $1.00 a pound plus shipping in 40# quantities.

    So the knowledgeable and thoughtful reloader is still ok for some time to come.

    +1 I use 4320 to get velocities in 8x57 with a 180g Nosler Ballistic Tip that I would never share on the ‘net. No signs of high pressure, as far as the brass/bolt lift methods are concerned.

    Did NOT realize that 4320 is no longer made...that’s a bummer.

    It is a very good powder close to 4198 and 3031 I am using 23 grains in my 219 Zipper with a 55 grain bullet. I'm not sure of the velocity yet but the accuracy is fantastic!

    We had 2-3 pallets delivered from CAI at 3 cents a round, used lots in my 1919A4 burnt out 2 barrels with it. Top covers would blow every 5-6 K rnds bent the crap out of them but flattened back out on an anvil they went back to work. God bless JMB!

    For bolt guns I would pull bullets and reduce by 5 grains or so as that was powerful ammo.

    I always paid for the rounds fired with the sale of the bandoliers crates and brass strippers sold on GB. Sorry but the golden days of surplus is over it seems

    ... I don't have the book at hand now, and memory can betray me, but was that what Kent referred to as "53 grs. load of nitropenta"?

    I used 3031 and 4064 in my 8x57 loads using the cheap 185gr Rems from Midway. They seemed soft and I couldn't imagine using them in 8mm Mag.

    I have been pulling some 8MM bullets from Egyptian cartridges with bad primers. I have been using it in .219 Zipper and .223 with very good results. It burns clean and so far all loads have been very accurate. Power seems to be inline with 3031 and possibly a little stronger. I have a few more loads to check for pressure signs. I haven't been able to test for velocity but will soon. I needed the powder very much and still have 4 or 5 hundred rounds to pull for powder. I will report velocity readings when my Caldwell chronograph gets here and testing starts.
