About 10 years ago I had the barrel on my 39A shortened to 18". Since then my eyesight has deteriorated, as it does when you get north of 60 years old.
I've now ordered a custom, stainless 24" target barrel for it. That should be in the post today

That means I'm going to have to go through the whole process of finding the most accurate ammo again. The old barrel liked CCI Standard velocity, and minimag. It also liked Winchester SuperX.
That brings me to the reason for this post.
My Marlin has a problem with the Winchester ammo, so while SuperX was accurate, it wouldn't extract about half the cases.
I did a bit of investigating and came to the conclusion that Winchester .22 lr cases have a thinner rim than most other makers, which allowed the extractor claw to slip off the rim. I had CCI so I didn't worry too much about it. About a year ago I had to replace the extractor, as the old one was worn out. Still had the same problem with Winchester cases. I've noticed a few other people at my club have the same issue.
Has anybody come up with a reliable way to fix this issue, other than not using Winchester ammo?
