    Will do Rick. I'll be sure to give you a heads up if either of us ever runs across another serviceable .357 K frame. Unfortunately the frames are the toughest parts to find. :(

    Ignition was not 100% reliable at 7 lbs so I cut a new strain screw that gives me a weight slightly over 7.5 lbs. I haven't tested it at the slightly higher weight yet. I honestly haven't seen any 617's run reliably at sub-7 lb, but I also haven't seen anything worked over by Randy himself. The mass driver hammer is a little strange feeling. With the rotational mass being moved higher up on the hammer, it definitely feels like it is slower to cycle. They are not a fast cycling hammer like their centerfire counterparts.

    My brother just finished cutting the forcing cone on his 617 and testing it out at the range this evening. You can cover groups with a dime at 15 yards and thankfully there are no issues with leading or bullet strike on the comp. Fouling patterns on the forcing cone look as they should as well. I'm beyond impressed considering this was virgin territory and everything was cut perfectly on the first attempt.

    Being rimfire mandates that. They are just a different animal from the CF guns. He put the mass out about as far from the pivot point as he could which is where we prefer to take it off of the CF hammers. That just doesn't work on RF hammers. I've never handled a piece of his personal work either and his wait time is epic last I checked. He seems to do things with them that nobody else can from the scuttlebutt.

    He put 650 rounds through the lightweight 617 build today and she runs flawlessly. :thumb:

    That thing is pretty radical. Fine work.

    Your gun looks real nice. I shot your brothers 22 after the steel challenge the other day. Pretty sweet. It would help if I could get used to a revolver trigger and quit short stroking it though.
