Hi Teresa, thanks for your help. Here are my responses to your questions.
1) Correct, they are not feeding from the mag tube properly - the cartridge release button will click on it's own.
2) When single loading the chamber, it feeds correctly. But not when feeding into the magazine.
3) Sometimes it ejects, but not always
4) We have tried the following loads: Game load 1 oz. 4 shot; 7/8 oz. 8 shot, all 2 3/4 in.; and 1 1/16 oz. 5 shot steel, 3 in.; 1 oz 71/2 shot.
5) The gun is cleaned after every use.
Let me know if you have additional questions. If I try calling tomorrow, should I ask for you since you would have background on the issue?
Thanks for your help - still new to hunting and guns, so let me know if my answers do not make sense.
