If you're interested in getting into a "build a gun" hobby, the Savage 10,11,12 actions are quite easy, accurate and plentiful. I have 4 that started out life as a 12FV on sale at Cabelas, and paid less than $250 out the door. Sold the barrels and triggers, bought used Target Accutriggers, fabricated or purchased bolt lift kits, long bolt handles, and quality aftermarket barrels, a variety of stocks.
They are quite accurate, easy to build, and I am able to frequently change calibers/chamberings. Takes about 30 minutes to swap out a barrel and trigger assy. using Northland Shooters Supply tooling.
Best of all, I've accrued a lot of knowledge in the process, which I find to be the most satisfying part.
You can find all the parts you need in the classifieds, action, triggers, barrels, stocks, rings, etc. And if you're patient, at quite a discount over new.
