Yes, the set trigger works perfectly, and the lock works perfectly with a strong main spring. The lock does not have a half cock notch as a lot of them didn't. I have another J Hayden that I had rebored and rifled to .40 gain twist by Bobby Hoyt and it doesn't have a half cock notch. I have taken many squirrels and won many matches with it though. My plans were to send this one to Bobby too, but I need to move a few items. Thanks, LK
