I recently bought a 10/22 that seemed to work flawlessly for about the first 150 rounds, now it hangs a spent case in the action every 4 or 5 rounds. Ive cleaned it twice, completely disasembled. CCI Blazers seem to be more prone to the problem but also occurs with Remington Golden Bullets, CCI Mini Mags, and Federal Something or Others. Everything looks ok with the extractor. Is this a common issue with break in or a possible problem that I cant see? This is my first 10/22 so im in the dark here.
