It's been years since I've owned a 10/22 and used the Butler Creek mags BUT IIRC they worked fine if you'll put a slight chamfer on the chamber of your 10/22 barrel. The sharp edge can stop rounds from feeding from these mags, take a 45* chamfer tool(like you'd use to drill a countersink for a screw) and by hand use it to cut the sharp edge off of the rear of the chamber where the round enters. Don't overdo it, just a little bit is all you need.
I've owned about 3 10/22's over the years and have put a slight chamfer on the chambers of all of them and they all worked like a champ with any mag I'd care to use.
