I have been using N560 in my Swedes for about 20 years now.Good stuff.
This 560 is a powder I've never used but might have to give it a try. THNX
Rl 19 and 22 seem promising, altho 22 is pretty Temp. Sensitive.
4064, 4895, RL 15 burn ranges
I know you like faster burning powders, but ya gotta be careful with them.

Yes DF, that's been my experience as well. I'm not saying they won't work but they have not given OPTIMUM performance for achievable velocities.
