++1 on test driving a classic 99 while you're here. We take trade-ins all the time!
In my experience you can chase the Savage 110 custom component shiny bauble thing until your wallet runs dry..., it's fun, but in the end you haven't really drastically advanced the weapon.
If you are chasing ultimate accuracy, or lightest weight.., keep us posted on your successes.
For my money, I would just modify the factory tupperware, it works, it's cheap, and in the end you'll have 95% of weight reduction you hoped for, plus saving time and money for the next greatest project!
Stevens 200 S/A in 204 Ruger, you can put the extra weight in a more accurate barrel, cut away the rest, go hunt!
