Thread: tight closing the bolt

Cant offer much advice but was the brass originally fired in the chamber of the rifle your loading for ?
I did have this issue once a while back in my 270wsm and it was fixed by winding my full length sizer die down incrementally until the brass chambered.
I'm not a fan of neck sizing over full length sizing but that's a personal thing, have you tried full length sizing a case to see in that solves your issue ?
