Im sorry, I know I am asking a lot of questions. Rem 700 police, 338 Lapua. When I chamber a round i have to slide the bolt fast and then I am able to push the the bolt down. However if I chamber a round slowly and then atempt to close the bolt, it wont move and i have to push foward and down more forcefully to close the bolt. Does this make sense> Like the bolt wont close unless round is bolt is very firmly against round. I have not experienced this before. If I need to be more clear on what I am saying, please let me know. Thanks for the help.
