Been There, Done That. The Richard's you want to use is on the East Coast. The Richard's Microfit is a big project. But the problem is that they do a poor job on Savage inletting. Check out the Vartac from Sharpshooter supply, http://www.sharpshootersupply.com . It's a true drop-in:
Brownells also sells a real nice 100% finished stock that, in profile is a dead ringer for a McMillan A3. If you can't wait for the SSS stock, and don't need the adjustable cheekpiece, consider the Zero Stock on sale now at Brownells. A steal at $192, finish sanded and fully inletted, with a bedding kit. Nice Laminate. I suspect it may need a little more tweaking on the inletting, but that's easy to do with wood.
,note: delivered stocks are dark gray, not natural as in picture)

Straight-drop pistol grip with dual, wundhammer bulges gives a natural wrist angle for better trigger control. Beavertail forearm and tall comb. Fully inletted, final sanded, ready to bed and finish.
