Several years ago I acquired 4 jugs of WC860 surplus powder when it was cheaper than now. By the time I got it, the urge to find something to shoot it in had passed. I'm now looking at trying to find loads(or even one) to shoot in a Ruger 77 .25-06 w/heavy barrel. Some time back I bought an assortment of .25 cal. j-words from a member here(I think). Might even try casting for the .25-06.
I've read several times that you need an oversize bore cartridge to come close to success with these slow powders. I an not real experienced in reloading for rifles other than a lot of reading and loading .30-06 for milsurps I would like to start developing a load or two for both light(87-90gr) bullets and heavier(100-117gr). It is doubtful that I'll do much more than shoot paper or coyotes(sp?).
Any advice would be helpful.
