What brass and primer are you using? We really need more info to be able to comment on this.
Have you checked your scales against check weights, is there something going on w/ the chrony, ...?
Do you have some other load data that would give us an idea on how fast or slow your barrel is...
Also, I guess it could be the lot of that CFE but it sounds 'way too slow to be just that.
Ok, just by chance........... are you shooting 129's by mistake? I know it sounds stupid but that's about what a 129 would give you, MV-wise.
Scales is right on. Horn. Custom ammo 123SST 2450 FPS , H4895 27.4 2273,,, ARC 27.1 2322 , AA 2520 2435, CCI 450 Horn. brass Dont have anything heavier than the 123"s
