Last year I took apart the action and cleaned the gun thoroughly except for the magazine tube. Ever since then I have had intermittent issues with the new shell not feeding properly from the magazine. It almost feels like there is not enough pressure behind the shell(s) to have them feed correctly. It doesn't happen when the gun is having shells chambered without being fired. The action seems to be working properly. It's just odd that this would start happening not long after. Do you guys/gals have any ideas? Thinking I may do what is mentioned in the following.
