Just put a Sig P220 in jail. Standard 4.4" barrel. I have a box or two of 230 gr. XTP's and was looking to make some hottish to hot loads for it. I have W231 and Blue Dot that would apply here. I've had fine luck with 6 grains of 231 and 185 grain XTP's, but it seems like it isn't a great powder for near max loads and high weight bullets. I have Blue Dot that I haven't really messed with yet in this application, but seems it would lend itself to near max loads. Anyone with any experience with these combos? Any advice would be appreciated.
Thanks,
Thanks,
