1969 High standard Duramatic .22 automatic . Not fired more than 50 times since new. Magazine was stolen. Went to good gun shop. They ordered a Duramatic magzine from tripple K. It came in .
With remingtom target loads it fed the shell high 1 0f 3 cycles) (just above the bore the shell front is in top of bore hole or just above it- you must push down on it and push the action forward to load it.,
. With CCI Minimags it was better and jammed only once in every clip of 8, almost always the 6 or 7th shell, then firing the last one.
With CCI stingers it shot 11 clips of 8 each flawlessly then jammed the same way in the 4th shell of the next 8 and 5th shell of the final 8 clip. Gun was very hot after the 11 clips of 8.
What is causing this jamming?
Does heat cause this problem?
New gun not yet broken in?
Why do more powerful shells work better?
Bad new magazine? Why almost always the next to last shell causes the jamming especially with weaker loads?
Any ideas?-
