I'm looking for insight on WC 867. Apparently this powder is from pulled down 50 BMG. How well will this powder work in magnum cartridges, 264WM, 7WSM, 300WM, Will it work well for '06 cartridges. 26-06 thru 338-06.

I have used quite a bit of the WC 867 and found it to be quite similar to Magpro powder(or at least the keg I have is ) Found it quite good accuracy and velocity wise in the 270 WSM I would suggest using it only with heavy for calibre bullets You might try it with heavy bullets in the 25-06 but it is way to slow for the 30-06 and 338-06. Hope that helps.
Back in the day the boys would drop a grain or two off Bullseye under the Kinsford line of powders to get them burning. Tricky business that.

I used wc867 in my 264 win mag the only problem is heat it's not coated powser .I even tried some in my 308 just low speeds .If there is nothing else it's a crap hit the fan powder .Its like h870 but makes higher pressure .They say you can even use it for reduced loads for 3030 have not tried that .I got a bunch of kegs for $40 each .It did have more preside in the 264 than the h870 did .I wouldn't pay more than $5 a pound for it but yes if there is nothing else it works in a pinch !
Man, am I lucky! If I had read this thread sooner and known what a sorry powder it was I would have never used WC867 with a 190 grain Nosler Accubond LR in my .300 WBY. There is no way it should have produced top velocities along with sub-MOA groups. And I would NEVER have attempted to kill the elk I killed with this load. I guess I'd better pay more attention in the future! And I'll be pulling my .300 WBY loads and dumping the powder on the yard. THANKS for saving me from myself, guys!

It worked good below 80 degrees no problem. It gave me high pressure above 85 degrees .Its not as good as h870 But it's fine with the powder shortage going on .Its pretty dirty burning have to really clean your rifle after 50 shots or so. It's better and being powder less for sure .You use to be able to buy 50 gallon drums of it for .20 a pound but you had to have a fireworks permit for it .
Obviously, WC867 is a very slow burning powder best adapted to large capacity cases with heavy-for-caliber bullets. If case capacity allows loading it to adequate pressure then it burns just as cleanly as any other powder of its basic chemical composition.
Smaller cases loaded with too-slow powders always result in a dirty barrel. WC867 is inappropriate in something like a .308 Win or even a .30-06. It will go "bang" and a bullet will come out the end of the barrel, but as with any powder in its burning range, you'll find plenty of crud left behind by the low pressure load.

Now that there is no powder left it might be a good deal hit the fan powder for your magnum loads .I used it in the 264 win mag and will probably use it on 7 mm rem mag and maybe some 338-378 loads .
