I am contemplating this on a WC Scott SLE 10 Gauge. The gun has a few problems with a bad restock and needed ejector work; however, the barrels and action are sound. The bores are .775 with 40 points of choke in each barrel. Chambers are 3. Ive heard that overbored 12s throw wonderful patterns, but would .775 be too large for a 12? Anyone have experience with this and who could be recommended to do the work?
