I realize this is outside of the realm of rifle smithing but on the other hand this community is more receptive to the notion that specific loads yield specific results. Some in this group have the tools, instruments, knowledge and skills to do it . Just looking for anyone who has turned their own chokes and any wisdom they would care to share including choke stock selection and choke dimensions. I have a lot invested in Briley and other removable choke tubes and the ones fit to the gun's barrels when the barrels were fit with gage tubes for skeet outshine the rest.
