What do I do?
Depends. With Ruger Single Actions I disassemble them and do a complete action cleaning and polishing, and using trigger jigs, a trigger job. I prefer the pull weight somewhere around 2.5 lbs. With the Redhawk and Super Redhawk, the springs are replaced with Wolff kits, the action cleaned and lubed and tested for function. Sight inserts may be changed, or a scope installed, depending on use.
I found the Savage line of rifles one of the best values on the market today. My Savage 93R17 BTV in .17 HMR proved to be an accurate and pleasant shooter. With a spare Leupold VX-2, 6-18x 40mm AO scope I had laying around, it makes a good short range varmint rifle. This is one that I removed from the box and used as is, no other modifications were necessary.
My other Savage rifles are homemade using bare Savage Precision Target Actions, prefit barrels from Brux, Pac-Nor or Shilen. Stocks are laminated wood from Sharp Shooter Supply or Savage. The barrels are threaded and chambered by the vendors, so all I have to do is install and headspace. Each rifle has several barrels in different cartridges and interchange with all the actions, some by swapping bolt heads. I never received an Erector set as a kid, so assembling my own rifles scratches that old itch. Each of these rifles shoot under .5" due to the quality barrels. It's a real fun addition to my hobby.
The latest acquisition was a Ruger 10/22 Takedown. It had a few problems, in that the barrel clamp was loose and wouldn't accept the barrel when tightened. That was corrected with a bit of fitting. It had problems with misfiring due to firing pin misalignment, which was corrected with a new pin, and the trigger was replaced with an aftermarket drop-in. Now it's a fun little rifle that is ideal to toss in the truck when traveling.
Now I am into the AR-15 scene, I consider the AR a giant 10/22. My current project is building a straight pull bolt action upper, to avoid California's loony Assault Rifle law, and determine the accuracy potential of the AR platform in a non-semiautomatic configuration. It is being built on a Fulton Armory side cocking flat top upper, using a Hart Barrel without gas port, chambered for .204 Ruger. If it pans out, the ground squirrel population will rue the day.
So that's what I do, just trying to fend off retirement boredom by keep my mind busy.
