our fun gun, a Remington 597 with bull barrel and laminated stock,
has started sulking. It used to feed and fire CCI Minimangs with no problems, but occasionally failed to fire some other brands. However, the problem has become far worse over the last few days. It will chamber a round easily enough but now hardly ever fires it. We can't see anything obviously wrong with the action or firing pin, but the strikes on the cases look exceeding light. What's the fix?
