I have a question for the scattergun experts among you.
I have this lovely little Remington Model 11 the local Merchant of Death let me have for a handful of East German coins and a mostly full box of Mike & Ike candies. I checked the proper adjustment of the friction rings on the recoil system, and the gun cycles fine. However, if you fill up the magazine tube with the maximum of four rounds, it drops the next shell out of the magazine on the ground upon firing the first round. (It will then cycle the rest fine without dropping anything.) If you load only three in the tube, it doesn’t drop a shell.
This happens regardless of whether you preload the chamber by hand and go 4+1, or just fill up the magazine tube and rack the bolt to load the first one from the tube.
