...and I picked it up.
I dug out my S&W M681-2 that had been through the S&W Performance Center about ten years ago and was worked on by Vito, one of the old guys. The DA isn't super light but is super smooth. I took it to the range with my .357 158-grain handloads that run about 1100 fps. The first few cylinders full were fine (B-8 at ten yards) but then holes started appearing below the black. I stopped for a while and fussed at myself, and then remembered something that Darryl Bolke talked about - load the cylinder, shoot one round, spin the cylinder and press the trigger until the gun goes bang, repeat until the cylinder is empty. No more holes outside the black. Imagine that.
