Our IDPA club did a night shoot, a few weeks ago, and I took my Delta, loaded with 200gr flat points over . . . more than ten grains of Ramshot Enforcer. It was supposed to be a can-you-top-this show, as a buddy was going to shoot 135's over . . . more than ten grains of AA #9, I think. He ended up missing the show, but I certainly won the award for most smoke. It was very damp and cold, and the smoke was just hanging there. The flashlight would illuminate the smoke, so repeat shots were a bit difficult. Muzzle flash wasn't bad, and ejection was very positive.
