We've all had problems with ejecting spent 22 magnum cases when using the hotter loads like CCI Maxi-mag +V, or other hyper velocity stuff. The slower powder used in these loads doesn't burn up completely in a revolver, and gets blown in around the ejector rod, where it rides through the frame.
I've fought this aggravating problem for a lot of years. Some time back, I read a post on another board(not sure which), about a possible fix for this problem. It sounded too good to be true, so I put off trying it for a long time. It definately "does" work, and now I'm sorry I didn't do it a long time ago.
All you have to do is remove the ejector rod, and grind it flat on the tip end. You don't want to make it completely flat. Just make the end look like a round nose flat point bullet. Be careful to keep the flat you're creating squared with the rod. If you angle it, it'll still let the un-burnt powder bind it up.
Here's my theory on how it works. The pressure from the same gases that cause the powder to be forced up into the ejector hole hit the flat on the end of the rod, and are redirected back out of the hole. This stops the powder from ever making it into the hole to start with. What ever the reason, it definately puts a stop to a very aggravating problem.
I used to have the perfectly clean ejector rod bind up sometimes after only one cylinder full. I'd have to work it back, and forth to get it free, so I could eject the cases. This has been a problem on nearly every Single-Six I've owned. Since I've done this very minor alteration, I've shot hundreds of CCI TNTs(one of the worst offenders) in one setting, without having the ejector rod bind one time.
