    Is any one using the surplus pull down powders to reload for a 300 Wby Magnum?
    Which ones and what starting charges are you using and how do they compare to the comercially available powders on the market.

    wc872 and 867 are basically equal to aa8700 or h870 and would be a good heavy bullet choice on the cheap for the 300 roy; I use some in my 300rum with 190 grain pills. Biggest problem right now is actually getting some of it. I only have only one keg of wc8723 so I aint selling any.

    I have used wc872 in a 300wby and it shot very well, but when using the same charge of h870 the velocity was about 200 fps less although the accuracy was a little bit better. I was shooting 190 gr. SMK.

    Thanks for the info guys. I still need to do some more research to find the best one.

    Wideners has both 867 and 872 in stock at present. They didn't the last time I checked before today. The only reason I'm not picking up a keg is I can't get rl25 or rl33 from them at present. The LGS's have those (and I'll need RL long before WC) so I'll buy from them and forget the WC until I need it more.

    Why do you consider these a better choice? I'm trying to get comparisons to regularly availible comercial powder. The way Home land Security is buying up ammo to keep it out of or hands this powder may be our last resort to continue our sport.

    It's simply more cost effective than H869 or H50bmg and similar to the other 50 cal stuff on the market. I've got one keg (wc872)of the two I bought two years ago; I'd buy another couple of kegs but I'm not buying unless I'm low on stuff at present. Your rifle will either like or hate these powders, much like the other slow ball powders on the market.
    I wish I could get more 5010, but H50bmg is the only thing really available in 50 cal stick that is remotely affordable at present. Rl50 is out there, but it's even more bulky and not that available, plus the price is similar to the other new stuff.

    Lefty A question for you regarding WC 867. I have used quite a bit of WC 867 that was purchased from Higginson Powders in Canada.I assume it is similar to the WC 867 availible from other surplus dealers. I have found WC867 to be very similar to MagPro, W785 or H450. Wc 872 is much slower similar to H870. There is also a WC860 powder that is a little slower than WC872 according to what I have read. Ihave not used any WC860. I'm wondering if you had WC860 & WC867 powders mixed up ??

    From what Wideners says, 867 is nearly as slow as 872 (they advise aa 8700 data for both), but that's why you have to be so damn careful with this stuff and load 15% or more down for the first few charges until you find where you've landed. I've pretty much just burned 872 and 5010 myself.

    magpro and h450 are rather different in their own respects with magpro being rather much slower.

    I couldn't agree more that you have to be real carefull with surplus powders. Regarding the burning speeds of Mag Pro and H450. I'm looking at a powder burn rate chart that I printed off the Ramshot website. They list RL 22 in the #137 spot being slightly faster than W785 in spot #138,followed by H450 in spot 139 and Magpro in spot # 140. Accurate 8700 is listed in spot # 144 being slower that 7828 in spot 143 and H1000 in spot # 145. H870 is in spot #149 being slower than Retumbo in # 148 but fater than VV 170 in spot # 150.

    Powder burning speed is relative to restriction, volume, and load (bullet weight) so two powders can be really similar in one round and rather different in another.
    I haven't burned h 450 for years but in the rounds I burned it in it was basically "ball" h4831 which would have put 7828 just a bit slower.
    In an overbore like my stw, magpro will act a bit slower than the 4831 class stuff. Magpro will not ever be found in my powder cabinet though, as it has ignition issues with federal primers.

    I shoot a rem 700 300 wm with 190 smks and all I use is wc-872 powder. I load 84gr in fed cases. Shoots better than h1000 for me.

    P.s. and cheaper.

    Thanks for all your help fellows I think WC-872 will be the one to go with in my 300 WBY.
