Sterling Mag issues

Thought I would post a picture of an issue I have had when I first received my Century/Wiselite Sterling.

It was stated in another posting that my rifle was not feeding some bullets well. I was experiencing jams in which it appeared bullets were diving into the sharp edge of the breech face/chamber entrance extractor relief cut.

I discovered after working with several magazines, that NOS mags were working just fine. Older, used mags seemed to be the ones giving issues.

I finally noticed the difference in feed lip geometry between like new mags and a few of my used mags. So I decided to try tapping an errant feed lip back into a position that I thought looked reasonable.

TURNS OUT THAT DID THE TRICK! For my rifle, in order for bullets not to impale themselves against that sharp transition edge from breech face into chamber produced by the extractor relief area, my magazine feed lips need to be parallel to each other.

I have included a photo to illustrate just what I am talking about. If you are experiencing any feeding issues, then I would highly recommend trying to bring the feed lips into a parallel position. I simply used a nylon hammer and tapped until the one feed lip came into proper position. Those two mags now feed 100%, regardless of bullet type.

I just posted this on another board where this same info has been shared....

Very decent of you gents to compose these images and then take the time to share them on the boards. These small data points make a very big difference to the shooting experience!

Just another bit of info. WLA cleans and refinishes one magazine to be included with each Sterling that goes out the door. This same magazine is used when the gun is test fired. I noted that some sellers are swapping the mag that is included for a used magazine, or removing the magazine completely.

Again gents, I really appreciate you posting this info.
