Iown two Remington 700XCR rilfes, one chambered in 300WSM and one chambered in 375 H&H. I just took them from the safe and tried to slip a piece of printer paper between the barrel and the tip of the stock. On both rifles the paper would only go in a little ways before it was stopped by the contact of the barrel and stock (less than a 1/2 inch).
Both these rifles shoot quite well. I doubt the pressure out there is the reason the gun won't shoot.
You are on the right track with powder, 4350 is excellant in the 30-06.
And, you are right, 57 grains behind a 165 grain bullet is a classic load.
I would be tempted to try a different brand of bullet. Then, of course, you could try different bullet seating depths, etc.

FWIW, I seat my bullets enough to obtain a 3.39 COL (base to tip measurement). You may want to try altering seating depth with your current most accurate load using the 165AB and IMR 4350.
Personnally, I would try everything else, different powders, primers, seating depths and so on before you start altering your stock.
