my nephew got a set. the lucky chuck got them FREE when he bought a new 10/22. bet that salesman was desperate- LOL. he loves then but is not a serious shooter. they work and load like a normal ruger magazine. they will handle 25 rounds out of the box without issue on bulk ammo by Federal & Winchester which is saying something. grab a set if you can afford them
as for the butler creek, i have a pair (Clear with red lips) (ok that sounds weird)
that clip together to make the same setup. Got them as a two for one buy when mags were scarce. I do still have issues when I load to 25. it started at ten but eventually worked itself out as I slowly increased the number or rounds that I loaded. now I can load 20 rounds without issues.
it took about a brick to get to this point. so not my favorite setup but better than only having 10 round mags
