A little preface; I find it interesting having come and gone through the years in this community to see that my rifles when I first built them fit solidly in the "Ultimate" category and seem to no longer match that appellation.
The following rifle was won years ago on a raffle, which sparked an instant decision to put as much money in parts into it as it would have cost to purchase. This caused a rapid slide into more and more parts.
The original configuration was a GM .920 barrel stuffed into a Fajen stock. In that config it wouldn't shoot no matter what I did. Until I took the barrel to a belt sander.
Second configuration was the same redneck'd GM barrel, synthetic sporter style stock with the hollow but filled with lead and spray foam to balance the barrel, VQ bolt, VQ TG2000 trigger group, OE everything else.
Third configuration was same redneck'd GM barrel, McMillan STC stock, VQ TG2000 trigger group, everything else Rimfire Technologies.
Fourth, and current, configuration is now Kidd, McMillan, and Ruger. Kidd products are 20" SS target barrel, bolt, 2 stage trigger group, recoil rod/spring, bolt buffer, pins, etc. Those are all mated up with the same old Ruger receiver nestled in a McMillan Sporter stock.
Also went through three scopes, cheap old Bushnell variable, a US Optics SN3 3.5-17 (until it went on the 308 that was being built), and a Leupold FXIII 6x42 that has been on it for quite a few years now.
Going to try and make it to the range tomorrow since spring is here in the Rockies (the North Platte is no longer frozen, been in the 50's, and it rained all day today

) and get some pictures of the gun and targets.
That makes me realize I have enough parts laying around I could build three other Heavy's if I only go buy some receivers
Edit: Wow. Looking at my join date that means I've had this one and only Ruger 10/22 for 9 or 10 years now. I think its time to expand the stable.
