A question for the sxs rifle builders. I have a C & H Avant Toute boxlock in 12 gau., ejector, not much invested. Barrels are usable but not the great, stock needs work, the action and mechanics are in good condition. If you are not familiar, the action already has free floating firing pins which should be a plus even if they need to be bushed. How suitable would this action be for conversion to a sxs rifle? I was thinking .303 / 38.55 / a bore rifle in 20 gau / suggestions. Thanks for any input --- John303.
