Straightening my catch/release on my MII Savage Classic helped, and I thought monkeying with the mag feed lips helped, but I still had frequent difficulty in getting rounds to chamber. Worse, I was getting shaved spots where the bullet meets the case mouth. Decided to figure out what the problem was and I got it
Stock magazines now work flawlessly, every time. I'm not going to unbend my c/r but I doubt there was anything wrong with it, either. The problem was that the extractor angle-tip was so sharp of a point and long that it would not let the rounds "jump" all the way into proper position on the bolt face. The rounds were therefore always at a slight angle when entering the chamber, so that they would stick and/or shave the bullet.
I took the blued, right-side extractor out and started honing on that point with a medium Arkansas stone from my 1911-trigger-job kit. I would take 2 or 3 thousandths off, then re-install and try feeding rounds. It took 4 or 5 round trips, but that's what you want -- go slow so you take off only enough to permit the rounds to jump all the way into the pocket on the bolt face. Only then are the rounds aligned perfectly with the chamber/bore. You want to keep the point, just not as sharp a point and not as long as the factory provided.
Now every magazine I have works perfectly, including some I had never altered in any way. No bullets get shaved going into the chamber! I can now close my bolt very s-l-o-w-l-y and the rounds still feed perfectly! In fact, I realize that is the proper
way to close -- push at a leisurely pace until you hear the round JUMP (they go "CLICK") into the bolt-face pocket, then go ahead and chamber your perfectly aligned round.
And, to answer your obvious Q -- Yes, both live rounds and fired cases still extract perfectly.
I have loved this gun but hated that I had to "single shot" it if I didn't want feed problems. Now it is the sweetist little feeder off 10-round mags you ever saw, first round to 10th
Couldn't wait to share! And, of course, proceed at your own risk. If you want to be super cautious buy a couple of spare right-side extractors so if my remedy does not work on your gun you can just toss the modified one and put a factory back in.
But for me it was simple, free and now I have the best-feeding .22 on the range! I LOVE IT!
