It seems to me that other than the cartridge itself (low power reload), the magazine often causes semi-auto cycling problems. Other encountered culprits seem to be the extractor and the ejector. I have been fortunate in that all my problems with correct cycling have been attributable to the cartridge load or the magazine. I also have not shot many non-military semi-autos, and the military rifle types I have used have all functioned perfectly while I used them. Some of you forum readers may have more experience with diagnosing semi-auto failures through a more extensive use of semi-auto hunting rifles of various vintages. Are there any quick visual hints which allow the shooter to determine just what the cause of a cycling problem is? Is the nature of the failure, eg, is it a stove pipe jam, a double feed, etc., a good indicator of the type of failure causing the cycling problem? Have any of you found that certain rifles are prone to a specific problem?
