I have one in 30-06 that's maybe 10 years old. The original magazine wouldn't feed the cartridges without hanging up. They send me a new one, and another new one. Finally the 3d one works ok. I tried winding the spring in one a turn tighter. That only made the cases stick tighter.

I'd like to get another one. Have they improved them any in the last few years? I don't want to pay for another crap one.
