With stock Ruger 10-round drum magazines, I get a lot of jams (mainly stovepipes), but I have almost no problems with an aftermarket 25 rounder (Butler Creek, I believe).

Anyone know what might be the problem? At $20 apiece, this is getting expensive! (I sent one back to Ruger a few weeks ago, but so far no word from them.)

My problems with misfeeds with the 10/22 were the result of using certain ammunition.While some loads work flawlessly,some caused feeding problems.

This is almost unheard of for the ruger factory mags to be less reliable than aftermarket mags. I assume that you are talking about fairly new mags. I have taken many of them apart and cleaned and wound up the spring for more tension. You might try that.

Right i have had some problems with cheap aftermarket mags recently( thought it was the rifle at first)in my ruger but not the factory one ever.

Usually it is cheap ammo for me that is a problem when it stovepipes in mine . Well except for some Eagle mag I bought they were terrible for jamming .

How do you take apart the factory magazines????

There is a hexhead screw on 1 end. Unscrew that and it pulls apart.

Check out rimfirecentral.com for your rimfire needs. I think there is a diagram and an explanation on how to clean the 10/22 magazines.

Since I started shooting CCI MiniMags in my 10/22 I have not had any problems.

Blunt nosed bullets like Rem. Yellow - jackets can also cause feeding problems in semi's along with the lower powered bargin ammo..............Harold

Sweet. I just got two bum magazines working again! Now does anyone know If I can take apart or clean my 25 round Butler Creek hot lips magazine?
