Question on powder??

    I came across a jug of about 5 pounds of what is labeled WC872 powder. Looks like a surplus powder, fine ball powder with flats. What is this equivalent to? Probably a large volume rifle powder?

    I kind of figured it was for large case rifles, I "inherited" a bunch of reloading supplies a couple years ago when a good friend passed away. He was into big bore guns like Weatherbys. His widow just told me to "get this stuff out of here."

    This page says you can somewhat use H870 or AA8700 data. Scroll down to the bottom of the list.... If you have a big magnum I'm sure it would be useful.

    IT works in the bigger cases fair depending on the actual caliber. Say for the 7mm STW you can get decent results with the heavier bullets, but not so great with lighter ones.

    In the RUM's results will vary again depending on bullet weights.

    With smaller standard calibers and cast bullets a lot of folks use it for informal target loads and simply for practice.

    Once caveat is that it leaves a lot of carbon which is sometimes a pain to scrub out if left in the bore and chamber very long.

    Like said above, that powder is very slow and meant for the 20mm.

    If you can find some WC820 that's good for the 30 Carbine and Magnum handgun rounds.
    WC844 is meant for the 223/5.56mm
    WC846 is meant for the 308/7.62mm

    I haven't been able to find any data on AA8700, I have a 45-70 that I could run 400-500gr bullets out of if it would be feasible. I'm real hesitant to just fill up a 45-70 case and seat a heavy bullet on top of it to try out. :D

    My Marlin 45-70 has a 24" barrel, if I could get a little bit of data I might be able to have a use for the powder.

    It is way too slow burning to work in 45-70.
    Even a case full with room left for a 500 grain bullet would give very low pressure and velocity.

    Even high performance 'Ruger #1 loads' use nothing slower then Varget for best performance.

    About all it will work in is the .50 BMG, or over-bore 7mm to 338 cal magnums.

    Funny thing is, even though the 45=70 uses a very big case that old straight walled cartridge uses the fastest rifle powders available. In reality back in the day Unique and 2400 were very popular fir loading the 45-70. I use either AA5744 or 4198 in the 45-70.
