Yeah... that gun started out as a joke. I bought the gun and left it standing against the door at TTI. As I walked out, I said "we ought to do a project with that Mosin"... when I came back the next day, Al had cut 9 inches off the barrel and put on a straightjacket.
I thought the wood on it was too good to chop up to accomodate the tube diameter of the bull barrel, so Mark (who had some wood at home) said, "no worries... we'll make a stock for it. We cut out the bench stock and kept certain features of the Mosin so you could recognize it as one.
Once we had gotten that far, I said "I'd like to mount a scope... and not a scout scope, but a "real" scope... " so we moved the bolt behind the action, and put a scope bridge over the action so I could mount optics.
When I shot the gun a few times, I decided to smoothe out the trigger, so I flattened a .45 case into a brass plate and slipped it up under the trigger to make it act like a single-stage trigger.
It was fun to do, and took three of us working about 30 hours over a weekend to create the first "Mosin Olympic" made onsite at TTI. After finishing it, I mounted one of those really expensive $95 6x24x50 Field and Stream scopes from Dick's sporting goods on it, and took it shooting.
Using commie copper wash ammo, it shot about 1 1/2" groups @ 100 yards. Using Silver bear, they tightened up to 1" using 203 grain @ 100, but stayed consistent at 300 using 174 grain Silver Bear ammo. Using my "home cooking", it's shoots dime groups at 100 with no trouble, which is under 1MOA... the best group so far was a 3 shot group shot when the range was closing, and I had already pumped 100 rounds through the gun in an hour... I can cover it with a dime...
