My new Tactical Innovations 25 round magazine for my 10/22 will not consistently chamber rounds without some jamming. I have tried various different 22 ammo with the same results each time. Any advice on how to fix the problem? I have already filed the edges of the lips slightly and found some improvement. I don't want to go too far in case I am just missing something. FYI: the factory 10 round mag cycles ammo no problem so I am guessing that it has nothing to do with the barrel. any advice would help.
