Remington 40X with a 30 inch Palma taper Kreiger barrel ,chambered in 308, optimized for 155's. Don't ask me where I got the chassis. I am sworn to secrecy....
I have or have had 700s in AICS 1.5, 2.0, and XLRs. At the time they were an inexpensive way into a stout stock with a stout DBM. Weak dollar and a lot of competition in the DBM market puts those days behind us.
When putting together a fixed position build I lean toward McM A5 or Manners T1/T4 depending on the barrel contour.
