[QUOTE="royinidaho, post: 659374, member: 2011"] Probably a little myth mixed with misinformation. My ball powder experience is limited to Ramshot Magnum, and US-869. Ramshot is too fast for my cartridge but what little I've tried it, it seemed stable from 40s to 80s in temperature. US-869 is a very slow powder and burns like coal at lower pressures. (Similar to WC 872). 869 is also noticeably temperature sensitive and gives poor ES with out a ton of load work. My cartridge bridges with stick powder and heavy for bore bullets and was designed for the slow burning ball powders. Ball powders are reported to cause less abrasion on the bore than stick powders due to geometry. Makes sense to me. Metering with ball powders is nicer than stick powder. Though my Chargemaster doesn't seem to care which it is metering. But it is faster with ball powders. I've also used a bit of Winchester 760 which is a really nice powder. Just my experience.
