Maybe get with Boyds and have them make a run of stocks for the special Rugers. Might could get them to hog out a little extra wood and shave another 4-8oz off... especially if its only another $75-$100.
If they went:
20-22" Stainless Sporter
Throated and Mag Lengthed to handle 75-80s
Boyd's Prairie Hunter(ish) Stock
Mini-Pic rail like the Predator
And they did it for under $500, I'd order one today
