Would appreciate any advice or input regarding a Canjar trigger, please. I have inherited a custom built rifle on a Sako L57 action (.22-250), aftermarket barrel, custom made stock, and Canjar trigger (unsure of model). The rifle was made in 1974, built by the prior owner for his own personal use, who by trade was a riflesmith specializing in custom fit precision hunting rifles. I have recently taken the rifle apart for inspection and thorough cleaning. Upon reassembly, there are frequent intermittent failures to fire. I have backed-off a little on the over-travel screw, without luck. I'm not sure how to approach this going forward, and to prevent further blundering, would appreciate any suggestions or guidance. Thanks.
