I have two 552 speedmasters that are about 10 years old. They both have not been shot very much and cleaned very well after each range outting.
This year they both missfeed, cases stuck in the chamber, etc.
I have tried different types of ammo, not clean as much, then go way overboard on cleaning. Still the same problems happen.
Is this a known problem with speedmasters??? They both are very accurate, but not reliable any more. Any help would be greatly appreciated.
