Question and comment: My husband purchased a 510 pump shotgun for me for protection / target practice. He fired one shell ( the correct one Remmington) and the gun jammed to the point where you could not move the pump action or take the gun apart. Cabellas where it was purchased on the 21st said they have to send it back and see if it can be repaired or they would replace it. I am so disappointed and feel cheated not to mention I don't trust the gun now at all especially since it is my first firearm ever owned. Has anyone experienced this or know what the problem with the giun might me. I am fearful that I got a total s---w job purchasing this particular firearm.
