Looking for help with 10/22 jamming issue

[NorTex250]

I've recently completed my first 10/22 build. When I first got tge stick rifle it would fail to feed rarely with the factory 10rd mag. It was more common with the butler creek 25rd and usually took place during the first five shots fired from a full magazine. Every time it jams it cuts a half circle groove in the nose of the bullet. I didn't worry about it much at first because I was planning on replacing the barrel anyway and I thought that would fix it. Since then I have replaced the barrel, picked up a BX-25, and switched from hollow point to the round nosed Winchester M-22 and the problem still happens. I have also replaced the stock and the trigger, but that should be irrelevant. The gun shoots very well and has become one of my favorites but I can't figure this problem out. Any help is appreciated.

I think your problem is barrel droop. Friend of mine had the same problem. First of all you only need 10 in/lb on the v-block. Most barrels do not fit the receiver very tightly. Get this and your problems should go away. Gunsmither Elevating Barrel Retainer Block Ruger 10/22 Steel I don't mess with the hi-cap .22 mags.

I don't think that is the issue because my aftermarket barrel is very tight but it doesn't cost much to try it. Thanks

Next time it jams, before you extract, check to see if the round is jamming high (top of breech)
or is it sitting low (bottom of breech). That half circle cut is the indicator. Jamming in my old 10/22
was caused by lead buildup on the feed ramp, or a misaligned magazine due to GSR buildup
in the mag well, caused by blow back.

I usually have to keep mine pretty clean to keep the jams away, especially with the copper coated rounds.

Don't forget the extractor and tension. Nor the bolt face itself. Spring tensions, recoil buffer/not, and a myriad other causes.
