I am going to be loading for a break action 223 soon. If I want full power loads I will used j-words. My real interest is in being able to load something 22 mag or higher in power, ideally with a meplat. I plan to powder coat the boolits and will cast out of fairly hard alloy (half lino, maybe with the rest COWW), so I am hoping I can get away with pushing these on the harder side for cast (1800 FPS?). If I can get away with not using a check on these itty bitty boolits, I would love to avoid the hassle.
