I have 2 BC steel lips that I bought from P&D (sponsor) a year or so ago for +- $100 shipped. Both mags are total garbage though and I wish I stuck with the original Ruger 10-round ones, which work for me 100% all the time and are cheap to buy. I use Federal Champion 525 packs, Winchester bulk packs and sometimes CCI Stingers and the f*ckin things (BC steel lips) would jam on almost every second round at the indoor range I belonged to. The bolt usually tears up (punctures) the rounds when a jam occurs and I literally have to pry the stuck rounds out of the receiver with a screwdriver, after removing the sh*tty BC steel lip mag for extra clearence.
Last time I've used them though, a fellow range member came up to me seeing that I had trouble with these mags. He said he owned a 10/22 as well and that the BC steel lip mags have a known fault in them, because they have too much forward play inside the mag well. He went to the nearby garbage can, pulled out an empty .22LR carton (the ones that hold 50 rounds), tore out a piece and then folded it a few times. He then jammed the piece of folded carton into the space in front of the mag (in the mag well) and told me to try again. Well, what do you know... all 25 rounds went off without a problem, with not even one jam... even in rapid fire! I guess he knew exactly what he was talking about and that the issue was indeed more common than some might believe... Once I shot all 25, I removed the mag, reloaded it, reinserted into the 10/22 (without the small folded carton) and tried again for comparison. First round went off, second one that followed got stuck in the receiver sideways and tore open... in short, same BS as before if I didn't insert the folded piece of carton. And yes, BOTH my BC steel lips mags have the same issue. As for my 10/22, I bought it brand new approx 2 years ago and I've always taken great care of it (it has low rounds on it as well), so I highly doubt it's an issue with the gun itself.
All that to say that those mags are total garbage and I have since abandoned using those two mags with great disappointment and disgust (I did not have the heart to sell this junk to someone else in the EE... mostly due to having a conscience). In short, if Butler Creek cannot make a mag which doesn't require a piece of folded carton to work properly, then maybe they shouldn't make mags altogether (or anything else that requires tight tolerances, for that mater). Just a thought...
