I bought a model 11 trophy hunter xp in 204 Ruger a couple years back and it occasionally won't pick up the next round out of the magazine. The bolt face just skims right over the top of the next round. It doesn't do this all the time but I sure don't want it to do that while I am out hunting. I am wondering if this is a common problem with and easy fix or if something along the lines of a larger diameter bolt will help?

Thanks for the help.
