I bought the 600 grain 458 socom moab mold, but I have no idea where to start testing loads at, I’ve got imr4227 powder. Some advice would be appreciated before I get tired of waiting and load something I’ll regret
There is another thread already started just two below this one. “HTC .459 600 grain MOAB” Started by Darksoldier300. I’m still early in my testing and it seems no one else has had a chance to shoot them yet. I will continue to post in the other thread as I gain more info.
