Measured them tonight and according to the hornady book they are in spec.
Buggered if I know, they definitely won’t chamber.

Maybe bullet seated too long and hitting the lands before case is fully chambered?
More likely a brass size issue though, e.g. chamber at the small end of normal specs, cases at the upper end.

I would pull a bullet and see if the empty case chambers.

1. most likely the base will not be sized down enough assuming you are using regular dies not "small base" ones.
2. Buy one of these JP Gase Guage If it fits in this it will fit in your AR

Have you tried this yet?? The other thing is if the bullets are not seated deep enough that can cause issues too.

if it shoots factory ammo without issue then its not the gun

Bullets not seated too long.
Rifle chambers factory ammo fine.
Tried a body die too, went through that fine.
Measured all dimensions with verniers and compared to hornady book, all within spec.
I have a small base die but when pushing a round in by hand it feels tight and I’m worried I will get a live round stuck.

Lube it and run it thru the die. It will be fine.

Run them through a FL bushing die with the bushing removed so it doesnt fuck with the neck tension

I reckon thats your answer tight there, case JP gauge will prove it for sure

body die, or FL bushing die and take out the bushing and decapper

They go through a rcbs body die and still don’t chamber.
Waiting on Sheridan case gauge to show up, then I guess I’ll buy a small base body die, lucky I’m stubborn because I will have spent more on fixing the problem than the ammo was worth!!
