The Black Diamond is about as good as it gets. Fine quality barrel, adjustable trigger, two action bolts, a real walnut stock and the barrel is free floated from the factory. i did glass bed the action of mine.

Recently i've been shooting some Triple Seven in my Black Diamond. The nipple is a TC from a sidelock gun. Never had a hangfire or misfire using the magnum #11 caps with 777. Not sure what effect cold weather would have on that. With #11 caps the 777 crud ring is greatly reduced in my gun. i always swabbed with alcohol before shooting.
