I know two smiths that fit 32" small bore Fox barrels in the white to existing actions. Was a ton of striking for sure. I believe your in the white barrels are number 1's and most likely the 30" barrels are number 3's. If you go to the Fox Book and look at the chart on barrel weights you can get a pretty good idea how much steel you need to get rid off. PS. If your 32" are not matted I believe Jon Hosford has the original Fox Barrel Matting machine. Good luck.
