Problem with bought "once fired" cases

[CROWMAN]

I have bought some Norma "once fired" cases, I have full sized them, but they will not chamber into my Howa 223.

I have re-sized successfully "once fired" cases many times with no problem and cannot solve why this batch are not chambering?

Any suggestions as to the reason?

Thanks for any/all replies

Will they chamber with no bullet? Check the cartridge length as I believe this can affect the position of the shoulder.

No, I have not loaded a bullet into the case, I am just trying the cases fully sized without any success in chambering them.

check length first then set up die and resize......keep adjusting die until it chambers.....or give to me lol

I've had this - needed to bump the shoulder back.

How do I bump the shoulders back?
