I have an Intertec 22 that I bought new several years ago. It's a kick to plink with but has NEVER shot more than about 10 rounds without jamming. I have tried several different types of ammo over the years. I have the plastic factory 20 or 30 round bananna style mag that came with it and a larger 40 or 50 rounder, probably ramline or something. I believe it will accept any clip that fits a 10-22. What are some really decent hi-cap mags that might feed better. These plastic things are P.O.S.'s with cracked and beat up lips, although they didn't work well brand new. Any suggestions to make this thing feed better are greatly appreciated!
