interchangeable powder question
Picked up a box of 36gr Barnes Varmint Grenades for my .22-250. My neighbor said he'd load them for me. Today I went up and barnes calls for either BL-C(2) or RL15 powders. He has a TON of powder, but neither of those, his are mostly older. My main question is: does anyone know if there is an older powder that could be substituted or do i need to go buy powder now as well?
also, if anyone has worked with these bullets and has a favorite recipe for them, I'd appreciate some info!
we are also loading Sierra 40gr varminters, so recipes for those would also be appreciated.
