A friend who owns an old MIROKU MK38 has an on-going problem with the bottom ejector, he is using World Cup cartridges with long brass.
1. Sometimes the cartridge drops past the ejector, not too much of a problem as it is easily removed.
2. Occasionally the cartridge sticks in the chamber after firing and is very difficult to remove - a major inconvenience in a reg. shoot - maybe two percent of the time
He has had some work done, the chambers have been re-sleeved and measure the correct diameter, the gunsmith peened the ejector dovetails to tighten the fit with the ejectors. First time out after the repairs yesterday, one out of 100 stuck and needed levering out of the chamber, He said the brass had expanded and looked "bent" it was protruding one side.
Has anyone see this problem, any ideas for a fix?

Correct, having owned three Miroku guns over the years I can tell you they're not as indestructible as some like to make out. The last used one I bought some 4-5 years ago had just this issue which was fixed by replacing the ejector, other minor fault were also put right but sadly it just couldn't be made quite the gun it was meant to be when new. There really is a "wear" point beyond which it's no longer economical or even possible to put matters right.
