From what I have seen in Jerry's posts and blogs, the 783 can be as accurate as a custom with a barrel swap, which uses a barrel nut so no gunsmith required, only a vice a gauge and a wrench.
The platform has huge potential.
My last build I went another route than Savage because it didn't have as much aftermarket support as i'd want, and Savage has got quite some support over the years.
With the 783 I wouldn't be happy at all with the available stocks.
There's only Boyds, MDT Oryx, and MDT LSS I can think of.
