Misery930
.270 WIN
I took my 930's magazine extension apart and noticed that the plastic cap is not hollow. In fact, it's nearly 1/2" thick and that could be valuable space for spring compression. I took a spring retainer that I had in my spare parts box and put it in the front of the extension. The retainer is partially open so I covered it up with a piece of grip tape. No particular reason for using grip tape, it was just what I had available. I have more wiggle room in the magazine after loading that 7th shell than I did before. Thought this may help if anyone wanted to get a little more space in their 930 magazine.
