I have 2 seperate questions about magazines
#1: I have a ruger 10/22, and my magazines never want to feed without stopping. Like the tension on the spring is down, or its just getting slowed or something. How can I fix it, or should I just buy new ones and take back the old ones..haha

#2: I have a remington 870 express super mag. and the magazine cap doesnt stay tight. It was one I had to put on with a sling kit. What can I do to keep it tight. I always have to take it on and off with putting a plug in it for waterfowl...thanks for the replies
