Re: Savage 10 upgrading
OK, after reviewing your posts and your Mauser project, I think I have something of a better grasp on your stage in the process.
Compared with the K98,the Savage is better configured to serve as a project platform. Components exist, and the design lends itself better to rebarreling. As I mentioned above, Savage has been reworking its offerings to the point where modification becomes less necessary. But, as with most specialized offerings, prices have also been creeping upward. Judging from the direction you projects have taken, I think you're looking to start less expensive, and invest more heavily in sweat equity.
The basic advantages of the Savage are available in the Stevens action, which is essentially the original Savage 10/110 minus the Accue-Trigger. Good replacement triggers are available, Savage themselves used the Sharpshooter Supply unit as an interim improvement while the Accue-Trigger was in development.
Good aftermarket barrels are available. I use Lothar-Walther, but many other excellent choices are available as well. Bell and Carlson and McMillan make excellent stocks. Barrel replacements go well with a recoil lug upgrade, I use Sharpshooter's item.
To save, I'd suggest Pac-Nor and Bell and Carlson, and in the meantime, you might want to experiment with handmade wood stock prototypes, perhaps built up from pine blocks. This can allow you to figure out the art of customizing for ergonomics, and configuring stock geometry for accuracy.
As special tools go, a barrel nut wrench (there are several types of barrel nuts, so count the spanner wrench holes in the nut and get the right one.), and barrel adapter blocks for a good solid vice should head the list. Getting the barrel nut loose the first time from the factory requires a major physical effort.
Scope mounts are important, For extended ranges, sloped bases help; most LR shooters use a 20MOA slope value. I like the Ken Farrel product, but it tends to end up with a higher optical axis, requiring cheek rise stock adapters. Burris Signature adjustable offset rings and bases can do much the same thing without adding excessive height, as well as allowing some provision to correct lateral scope mounting misalignments.
The important thing is to get reliable components and stuff, install them right, and get the piece up and running. Avoid the masterpiece obsession until you're past the apprentice and journeyman stages.
Start simple, keep simple, and don't get hung up on details and detours.
