I asked a question about bolt lube in a forum above. I mentioned that i had some rubbing on my bolt body from working the bolt up and down. One fella said that my lug isn't touching the properly. I installed a rifle basics trigger in the action when i got it and it feels like the bolt is stiff. Is there any connection here? Do i have a problem, and if so how do i fix the problem. The action is a stiller predator and the bolt is spiral fluted. The rubbing marks are on the tops of the fluting. Please help as i do not want to ruin this action. Thanks Lee
