Hi, just recently purchased a Remington 780 which is the first pump type shotgun I've owned. What I want to do is have the magazine loaded with a few shells but not have one in the chamber. If I ever had to use this I want to be able to slide the action down and up thereby being in a position to shoot if necessary. I have an ideal that if I slide the action down I can load a few shells but what happens when the slide is push back forward. Is a shell in the chamber? Can you load the magazine without having to bring the action to the rear? I'm thinking maybe I can load this by just pushing shells into the magazine thereby not having one in the chamber and not having the hammer spring in a cocked position. The gun is for home defense and will sit more than being used for anything else. I've had many guns over my lifetime but am just now getting back into purchasing them again. I'm sure what I had thirty five years ago is probably changed a bit these days.
