44 rem mag and 30 carbine powder
I use this for 44 rem mag and 30 carbine loads. The old wc military powders had issues in cold weather. I live in alaska. I’ve found 4227 much better at frigid and below zero temperatures than h110. Loads well and shoots well in the application I’m using it for. I have thought about working up some 45 long colt and 454 casull rounds with 4227 but haven’t researched it and haven’t done it, not sure if it’s even feasible.

Good consistent groups out of super blackhawk 44mag with cast and some of the best accuracy I've had in my 300blkout with 150s
