Farley
The originol Farley's had the same thread as a Remington 700, or at least nominolly it is the same. I have sold quite a few take off barrels from my Farley Benchrest Rifles to local shooters with Remingtons. You can chuck the barrel up, cut the shoulder back for the recoil lug (if needed), and establish the counterbore where the cone used to be. It won't be a full "three rings of steel" like a real Remington, but works just fine.
Many shooters also have me just run a 6BR reamer into the 6PPC chamber, as the 6BR seems to be more popular with the non competitive shooters.
I have seen some of these cobbled together things shoot phenominolly well.......jackie
