More on WC852, this is a rolled double-based speroidal powder original purpose was for loading Cal. .30 APM2, suited for 165-gr. and heavier bullets. Much of this was sold by Hodgdon as H414, burning rate is similar to W-W760. Some later lots of H414 after the milsurp powder was gone were 760BR, which was an older 1970s version of 760.
WC850 was not rolled, but a true spheroidal powder, from Korean war era, originally used for loading cal. .30 Ball M2. This powder was associated with chamber ringing problems in the .30-'06 when the powder was oriented towards the primer leaving lots of airspace in the case. Much was sold by Hodgdon as H380. Great powder in the .22-250 with 50-55 gr. bullets. Also well suited for .300 Savage, .30-30 and .308 Winchester with bullets up to 150 grains. Do NOT load in applications resulting in more than 10% airspace. Do not attempt reduced loads with this powder.

I've used quite a bit of IMR 5010 and WC 860, but almost exclusively in nominally .30cal. (including metric) cartridges with CB's weighing at least 160gr. although heavier is better, and always with large rifle MAG. primers. Of the two powders mentioned, IMR 5010 is harder to measure, less clean burning, and harder to meter via a powder measure (the old Ohaus Du-O-Measure is an exception), and more prone to high extreme velocity spreads than WC 860. However, it can be tamed by using small amounts of case filler*, e.g., powdered bran or spherical shot buffer, 0.3cc - 1.0cc depending on the cartridge and loading density. Btw, if you use the latter filler, you should store the loaded rounds with the primers facing you so as to prevent the filler from migrating into the powder charge.
Since the burning rate of milsurp powders varies from lot to lot, it's best to start low, chronograph your loads, inspect your brass (and target!), and then work up to a given velocity. For me that's ~1,800fps. For the 7.5 Swiss, the .7.4 x 54R, .30-06, and 8 x 57mm Mau. with CB's weighing 175gr. - 195gr., I'd start with 46gr. of either powder. With 5010, you'll probably need a bit of filler to boost pressure and efficiency. Btw, my working loads were no more than 49gr. 5010 in the aforementioned cartridges and CB weights. Ditto for WC 860, but WITHOUT A FILLER.
If you happen to reload the 7.53 Argentine/Belgian Mauser as I do, you'll find that 42gr. WC 860 + 195gr. CB + LR Mag. primers works well (never tried 5010 in this one) in the Modelo 1909. I also found that 43gr. + .5cc -.7cc spherical shot buffer cleans up the case necks to an amazing degree v. 44gr. WC 860 and no filler. If you search the archives of the Cast Boolit site under WC 860 and IMR 5010, you'll find more information. However, these 2 powders weren't designed with straight wall cases in mind and will be incredibly dirty burning in the 2 you mentioned unless you duplex them (can't help you there). Hell, they're not exactly clean burning in the bottle necked cartridges I named either unless you go to full house charges.
*With either filler, you want just enough to allow the CB, when seated, to lightly compress the powder charge

Cool! I got some WC844 from a friends estate, now I know what to use it for. Thanks!

Ed and Molly,
Thanks too. My old buddy and I just got 4 or 5 different milsurp powders out of an estate. The guy had even pulled some old Russian bullets and saved the powder in peanut cans. He labeled it, but we didn't want to mess with it. By the time you worked up a load with it, there wasn't enough to load much with. We put it on the garden for fertilizer.
This is good reference info and I'm going to print it and put it in my load manuals. Thnx again...............Dan

Addendum: IMR-7383 is 50 BMG Spotter tracer powder. suggestion, across the board, and irrelevant of bullet weight: is to take a fired, FL-sized, primed case and fill it to overflowing. Level it even with the casemouth, and weigh it. Ten times, and average that weight. J-bullets start at 85%, cast at 75%. Go up in 1-2gr increments depending on case volume and caliber, and slow down to 1gr at about 95% charges. That is where it shows signs of pressure spikes.

Hi new member ned info on wc860 and wc852 for reloading would like to use thewc852 for my 7mm-08. i need to verify that i should use h414 data on an equal basis Can you help? Thank, Joe feel free to share with anyone that may help.

New member today--need to know if i can use h414 data directly with wc852? Thinking of reloading my 7mm-08 with 140 gr bullet for deer.
Thanks, Joe Scarpace

Hi Joe, welcome to the forum. I can't answer your question but maybe someone who knows will see this.

Joe,
New here myself. Two sites other than here, you may get answers about this powder are Cast Boolits, and longrangehunting.com, these are two places I have seen the surplus powders used more than anywhere else.
Hope this helps

This is a two part question. First, I'd like to hear about what some of you have done with the very slow surplus powders, such as IMR 5010, WC860, etc. I have a few jugs and am looking for ideas to make use of them. Second, uses for Data 68 which is supposed to be equivalent to AA2700. I got a couple jugs back when it was available. More specifically, I'd like to try all these powders in straight walled cases, namely 45-70 and .444 Marlin. Anybody been there? I'm looking for ideas.

Very good info here.. Now if I can find some powder for a LOW price for 223 that would take care of New Years resolution #1

I'm a new member looking for any information on reloading for my Barret 50BMG. I have experience and tools for reloading jacketed bullets, but I want to cast and load some lead bullets for target shooting out to 700 yards. I ordered a mold from CBE casting an 833 gr gas check Postell type bullet, their 512965 design. I have a five pound can of Hodgdon US 869. My Barret is their M99, a bullpup design, and I hesitate to put my head next to the chamber and pull the trigger on an untried experimental load.
Any advice would be much appreciated.
Thanks,
Painless Doc Cooper
