I recently acquired a 722 in 222 Rem Mag. I would like to start with 50gr projectiles. I also have quite a bit of RL10x that I would like to use, but Alliant doesn't publish any data for the cartridge.
Nosler had 55gr data using RL10x, but for their load looks really anemic. Barnes has data for the 50gr tsx with RL10. The listed max for that load is 24gr, so I'm thinking using up to 24gr with a lead core bullet is likely going to be in the safe range.
That's really all I have been able to find. Does anyone else have any experience with the 222 RM and Alliant powders?
I also have a ton of CFE223 that I could try too, but I haven't found any data whatsoever for CFE223 in the 222 RM.
