Never used it but it would fit in with my self imposed limiting of only using Hodgdon/Winchester/IMR powders for the foreseeable future.

What kind of powder is it? Ball, flake, flattened ball, cylindrical?

I do have a friend that swears by it in the 45ACP, I'll have to ask him what his load is again.
That dude is like Methuselah, I mean he has been shooting since the Chinese invented gun powder!

I'll make a rendezvous with him tonight and find out.

p.s. Was there any more where that came from?
