Reloading for my Rem 722 in .222 and I have an issue relative to one test round refusing to chamber without being heavily forced......making me nuts. I have no issues with factory rounds for this rifle; they load flawlessly and are accurate.
I am using Winchester once fired brass that has been FL sized, trimmed to the correct length and loaded with
22.5 gr under 52 gr Sierra HPBT (this is the problem round).
23 gr under 55 gr Nosler SBBT.
Using the same die settings for both and the rounds loaded with the Sierra bullets will NOT chamber without a lot of force and in some cases I can not close the bolt at all on these rounds. No issue with the rounds carrying the Nosler bullets.
Both completed bullets are within spec of the OAL and neither of them show any signs of touching the rifling once chambered. But the brass cases carrying the Sierra bullets show marked and shiny brass on the head stamps after loading attempts....
In over 50 years of reloading I have never encountered this and there must be something I am doing, or not doing, to cause this situation.
FWIW - I am in the process of pulling the Sierra bullets using a kinetic bullet puller and them bullets are in the neck so tight that there is an imprint of the brass mouth on the copper bullet cladding. I counted 30 heavy blows with the bullet puller before the round left the brass case.
Good night Chesty, wherever you are......
