    Kazan Manufacture Surplus Powder

    Recently, I have seen 16 LB auctions on GBroker/Ammo/Ammo Reloading of Kazan, Russia manufacture powders FSP-680, FSP-747, FSP-749, FSP-759, WC-846, WC-857. The FSP-759 Smokeless Rifle Powder 8-LB jug label reads: "F.S.A.A.P. (Fort Smith Arms & Ammunition Plant) Propellants"
    "OEM Rifle Powder manufactured by Kazan Powder Plant for Russian military & Pulled Down for re-sale at FS Russia Nitrocel Ops #1(FSAAP). Powder loads similar to commercial Ramshot "Big Game" and slightly slower than Hodgdon H380."
    The other powders have similar labels with different similarities/characteristics/burn rates. That said, I do not see FSP-759 listed in any cross-reference only single-different Kazan Quikload data. Well, reloading since 1970 I couldn't resist the price and/or challenge. What I have to date on Kazan manufacture powder similar to if not the same as their military-use labeled FSP-759:

    Kazan gunpowder plant in Kazan, Russia manufactures the Irbis brand rifle powders as well as FSP-759. FSP-759 is similar to, if not the same as Irbis 30-06S powder manufactured by Kazan/the same Russian plant. Note the web-obtained loading data (first-below) is similar yet different from the H380 30-06 loading data reprinted from Hodgdon and SPEER reloading manuals (last, below). Note the Irbis 30-06S data is NOT MANUFACTURER or LAB-PROVEN/CERTIFIED and/or certified applicable to FSP-759, thus for educational inquiry only noting that the Kazan/Irbis powder loading data is my rusty translations from the Russian web forums/links below.

    Irbis brand 30-06S (30-06 Springfield) cylindrical rod-shaped powder loads for the 30-06:
    ===> NOTE: cylindrical (rod shaped) powder loads usually does not drop/pack as densely as spherical (ball shaped) powder like Hodgdon H380 HOWEVER several lots of FSP-759 have been reported to be super fine extruded, short cut for improved metering and may approximate spherical (ball) powder loading.

    ===> “During this period, it was found that the nomenclature of sports hunting gunpowder is less in case of quantity compare to the foreign ones and was insufficient to provide increased consumer needs in Russia. Therefore, the 'KGTS' intensively carried out works in the direction of expanding the range and improve the quality characteristics of hunting and sporting gunpowder[3]. At the factory was developed and launched into a series 17 brands of new hunting and sporting gunpowder for the shot of 12,16,20 caliber for rifles and hunting shotguns, sporting and service weapons, including import calibers 5.56 and 9mm. From these, for the first in Russia was developed monobasic and dibasic pyroxylin-grained powder brands of the family 'IRBIS', such 'IRBIS PS', 'IRBIS PN', 'IRBIS-luger M', 'IRBIS-Lueger M', 'IRBIS 223 Rem', 'IRBIS-KARBAYN', 'IRBIS 7.62x39', 'IRBIS 308Win', 'IRBIS 7.62x54R', 'IRBIS 30-06S', 'IRBIS 30-06SM', 'IRBIS 338LM', 'IRBIS VL-1' 'IRBIS VL-7', 'IRBIS 24', 'IRBIS 24M', 'IRBIS Sport 32', 'IRBIS Sports 32M', 'snow leopard 410', 'IRBIS Hunting 35', 'IRBIS Hunting 35M', 'IRBIS Magnum', 'IRBIS Magnum M'. Developed from the 'KGTS' hunting and sports powders are commercially available, have a high level of quality and are available in amounts up to 50-60 tons per month for a Russian ammunition plant and for export.”

    The Russians killed tens of millions of Asians, and tens of millions of Europeans, and tens of millions of Russians over the last 100 years. They may be pretty good at making powders.

    IIRC the US military shooting team were using Russian primers at one time. I bought 10’s of thousands and no regrets.

    I would try their powders if the price was right.

    I don't have those powders but I do have some Russian powder here. Maybe a little dirty or I don't quite have the pressure worked out but no other problems with it.

    At $43 per pound, they can keep it.

    Auction prices are variable. I picked up mine for less than 2 Benjamins (16 lbs--$200/16lb = $12.50/lb)
    try GunBroker auctions search for "16 LB" without the quotation marks

    The list you posted has two powders that seem like the don't belong, WC 846 and WC 857. Any of the WC powders ive used are some kind od spotter round powder or 20mm vulcan powder that i believe was made at the ST Marks plant????

    No these are not triple-base IMR 7383 spotter powder used in spotter 50s. WC-857 is the double-base pulldown main-propellant charge for the 50 cal tracer (see General Dynamics (St. Marks) link below).

    WC-846:
    https://fedarm.com/product/wc-846-po...le-like-bl-c2/
    https://www.gunbroker.com/All/search...%20846&Sort=13
    "This military grade smokeless powder is a ball-style powder manufactured by Saint Marks (General Dynamics) for the US Army. It was pulled down in 2018 for the Fort Smith Arms and Ammunition Plant (FSAAP) at Lake City Army Ammunition Plant by certified Lake City & ATK Engineers. It has been certified for re-use, pressure, burn rate, accuracy, and unique lot numbers by both entities under ISO: 9001 standards before packaging for re-sale. This is excellent powder for use with: .223 Rem., 5.56×45 NATO, .308 Win, 204 Ruger, 17 Remington, and many other calibers. It loads very similarly to Hodgdon BL-C2 powder."

    Thanks for spotting my typo/error. It is WC-867 not WC-857

    I must be confused, in the 1st post you list both of them as Russian made powders and in the 10th post you say they are made by general dynamics. Am i missing something???

    Yes you are missing that the WC-xxx powders are made at and labeled by General Dynamics/St. Marks in Florida then pulled down for re-sale to to the general public at Lake City Ammunition Plant in Independence, MO 64056--see fedarm link/description below--, like this listing (hover over the image with finger/mouse to enlarge):
    https://www.gunbroker.com/item/905284806
    https://fedarm.com/product/wc-867-po...ike-h870-16lb/

    The FSP-xxx labeled powders are Russian manufactured powders at the Russian Kaisan Powder Plant then pulled down for re-sale by FS Russia National Ops #1, and repackaged and distributed by Fort Smith Arms & Ammunition Plant (F.S.A.A.P.)--see fedarm link/description below--for sale to the general public at Fort Smith, AR 72904 like this listing:

    The Kazan powders, FSP749 (flake) & FSP759 (stick), recently offered by "Fort Smith Powders", via auction on GunBroker are interesting, though care must be taken in use.

    They do Not act precisely the same as most canister powders offered to US reloaders, re; energy gain per charge increase or behavior at "maximum".

    I have found abnormality in pressure curve behavior, and these really DO NOT act very nice if you take for granted the burning rate recommendations made in the auction as a guide for interchangeability. (Yes, that's normal long standing advice, but I find especially apt w/ these two offerings that I have tested.) Had my first "conversion" of a 243 Winchester case into a "belted" version with FSP-749 when using guidance on burning rate from the auction...

    I have developed reasonably functional (non-pressure tested) data with FSP-749 in 243 Win, 8x57, 35 Remington, and a 41-40 Wildcat that I developed to use in a modified Steyr M95. I have developed data for the FSP-759 offering in 243 Win, 260 Remington, 7x57, 30-06, 8x57, 35 Whelen Improved.

    In testing I did find that what seems like a great Max load one day from 2 shot chronograph testing may well provide startling signs of overload the next in larger group firings. May be normal statistics, may not.
    Conversely, they do apparently have some useful characteristics if a reloader is observant.

    I have decided these are fine, but I trim velocity expectations to slightly below the max of comparable powder data (again, I found that to NOT be comparable powders suggested in the auction listings). I keep a close eye on energy per charge weight, fired case inspection w/ a loupe, and really am leery of using in guns w/ low margins for strength.

    Why did I buy these?
    Something to try, it's the experimenter in me, as well as having trouble getting canister powders this year, and past experience of using many powders in cast bullet loads for off-hand rifle practice encouraging me onward. Generally it is harder to get in trouble w/ unknown powders when trying for 30K psi rather than 60K psi, and that is why I bought the FSP-749 flake. My off-hand practice burns a fair amount of powder, and I got tired of using my canister powders that worked so well in target loads when I could not replace them.

    So: Here is some data I worked up, complete with Notes from my own evaluations.

    Please understand that the text formatting went wonky when I copied over, so I have fixed best I can. It it looks odd, try stretching or compressing window size in the horizontal direction.

    PLEASE NOTE THAT THIS DATA IS NOT PRESSURE TESTED, WAS GATHERED FROM LIMITED TESTING IN LIMITED CLIMATIC CONDITIONS AND LACKS SUITABLE SAMPLE SIZE TO UNDERSTAND VARIABILITY OR STATISTICAL ANOMALY.

    That said:

    1.125 (2) @ 100 yd CHRONOGRAPH LOAD Looked fine, no bolt lift issue, rounded primer outer edge, no rim flow into EJ, etc. Edge of firing pin indent sharpened though, and machining marks on tip were transposed to primer cup. In group test, second primer failed, primer riveted and shined by bolt rotation, one narrow band on head shined by bolt rotation (EJ slot), and I stopped shooting group.

    Acting somewhat like BLC-2 for velocity/charge BUT higher evident pressures

    Looks like any Compression is NOT a good idea in these initial tests, and pressure may come on Suddenly.

    This statement on Compression from 70 gr load on 243, assuming equivalent to 4064.
    HOWEVER, this powder actually acts much like IMR 3031, and so it likely was an overcharge creating high pressure and Not compression.

    Well, TurnipEaterDown. That is a very helpful post. Thanks for this data and reminds me that I have some surplus from Jeff I need to get busy with. 48lbs I've not had time to work up data on. Very slow powder but the .416 I purchased on a whim might be just the ticket for that powder, others with Nobade's insightful help I'll need to duplex.

    Plenty of US powder is available if you want to wait or search. Why take chance on unknowns? Save a few dollars? no.

    Looks like any Compression is NOT a good idea in these initial tests, and pressure may come on Suddenly.

    This statement on Compression from 70 gr load on 243, assuming equivalent to 4064.
    HOWEVER, this powder actually acts much like IMR 3031, and so it likely was an overcharge creating high pressure and Not compression.
