Hello, Not an avid poster but have been a lurker for awhile now. Well I finally got my first rifle, a good cheap little Winchester Cooey Model 64B .22LR semi-auto. Got it cheap and still shoots true but it jammed every shot so i took it fully apart and cleaned it and now it only jams every 3rd shot. What else should I check? Thanks.
