Thanks for the detailed instruction. I appreciate your attention to the nuances and forewarning me of the pitfalls, such as the drill bit catching and pulling the bit in faster than I'm expecting.

I have acquired just now an appropriate stud and swivel set of the "Uncle Mike's" brand. I'll probably make this modification fairly soon, although possibly not right now as we are having about 6 out-of-town family members coming in to spend the weekend tomorrow afternoon (celebrate my son's 18th birthday, not Super Bowl related).

Out of curiousity, do you recommend any particular sling? I use 1" leather military style slings for my hunting rifles. Should I just use one of them or should I get another sling dedicated for shotgun use? It might be a bad idea to expose the leather slings to water -- that might screw them up. Any comments on this subject?
