I was out at the range on Thursday breaking in my 10/22. I was trying out the stock mag, BC mag and Shooter's 30-rnd mag (all steel lipped).
The stock mag was rock solid, but both the BC and Shooter's gave me the odd problem. Thing is, I don't know if the issue is with the gun or rifle at this point. Huh..?
That being said, the steel lipped shooter's ridge hasn't given yet a reason to believe it is worse than the bc.
Time will tell, planning on heading back to the range within a couple of weeks. Keep us informed how the S/R mag works for you.
