Edit: Unlike the Timney 510 trigger for the Rem 700, the 783 Timney trigger has a very thin trigger blade. I like the look and feel of the wider blade on the 510, than I do this blade. That said, the Timney for the 783 has no creep, and breaks nicely at a safe 3lbs.
Finally an update; I am shelving the Boyd stock for now, even though I purchased a bottom metal unit for the rifle from Pacific Tool & Gauge. I just ordered a complete XLR Element 3.0 chassis for this build. The decision did not come lightly, as dropping a "G" on a $300 rifle that I have not even shot yet, was a heck of a wrestling match. However, I was PM'ing a member on the Snipers Hide forum, who has just such a setup, and he said he loves it, and highly recommended it. Chassis options are slim, with XLR having the better option (in my opinion). When it arrives, I believe I can finally get a shooting report published...
Here is the pic of the pre production model that XLR made for the 783:
I went the PDN Gen IV route on one of my 700s. S/S 700 Receiver and Krieger 29" Heavy Varmint Contour Barrel with Break. .308 Palma Set Up. Bigs N Andy trigger Nightforce 8x32 BR Scope. 20 MOA Rail with Burris Signature Z Tactical rings.
While I am waiting for my chassis to arrive from XLR, I went ahead and took my original Boyds walnut stock, and PT&G bottom metal over to my gunsmith to have the stock milled for the metal. I may never mount this configuration together, and will probably sell the combo... As I have ordered a new barrel for the 783; an X-Caliber in 1:8 twist; M24 contour. This will go on the action, and sit in the XLR chassis for final assembly.
