WC 872 military surplus powder

[BanjoGeek]

I acquired 9 pounds of WC 872 military surplus powder and can't find any intel for it. Anyone out there have any resources where I might find loading data and applications? Thanks in advance.

Looks like it's been used in the heavier calibers like 50 cal and some of the other magnums (rifle).

Wc872 in M1 Garand

Have read much about wc 872 in 3006 and much about the pressure curves for the M1. I get good accuracy in my 03-A3 with a full case and 311284 but I am hesitant to shoot this load in my M1. Other sources say the gas system is made to handle the volume of gas that 50gr of powder produces...

I still have some, leftover from a jug I bought many years ago because it was so cheap (something like $3/lb back then).

I never used much of it because it was too slow for anything I load. In the .300 Win Mag (the largest I load for) it was marginal even with heavy bullets. If you don't mind lower than average velocities with a case full of powder, then it works fine.

If you load .300 Weatherby and bigger, then it's good. If you shoot the big guns like .30-378 on up to .50 BMG, then it's ideal.

I still have several OLD cans of H570 sitting on my shelf, that I picked up from an estate sale about 20 years ago, also too slow for my purposes.

I would have been looking for data BEFORE.....I bought the powder. BUT that's just me.

Yes, normally that's the wise thing to do.

Sometimes though, you run across a deal that's just too good to pass up. In those instances sometimes it's prudent to buy first and ask questions later.

What cartridges are you hoping to find data for?

Mostly 30-06 & 308 but if I wind up selling it I would want to know what other uses there are for it. It fell into my lap and you never have too much powder but now & then it makes sense to turn it into something else.

You technically could use it for those rounds, but velocities will be very low, even with the case completely full. It's way too slow to be efficient in all but the biggest rounds.

Burning rate is similar to Accurate 8700 (some say they're the same), so that might be a good place to start.

Have you loaded up any of the WC872 yet? I am seriouslly considering buying some for use in 7.62x54r, 30-06, 300 win mag, 25-06 and other cast bullet loads.

You can use aa8700 data for the WC872 and this 2003 vintage pdf has 8700 data for a number of cartridges.

Edit: the data with (L) is for cast bullets.
