I just started working up some loads for my 2 new 22-250's. The books say OAL to be in the 2.350 range but I measured my chambers with the wooden dowel methed and come up with 2.500 OAL and longer with 3 different bullets. (40 and 50 grain nosler balistic tips and 64 gr winchester power points) I'm using H380 powder so far. Is 2.500 too long?
