Metalguy, Pay particularly close attention to what Ron Vella says, for he speaks the truth gained from considerable practical experience. Don't consider bushing strikers as too difficult or complex, for it, in reality, is a simple process, compared to all the metalworking you need to do for a conversion. It has been my experience that it is always best to bush strikers in any and all shotgun to double rifle conversions, unless already bushed with proper diameter strikers for double rifle conversion. Not doing so means that you are risking doing what happened to Ellis Brown at Pine Tech College, MN. which I saw happen on site. The event is described and pictured in his book. Elmer Keith once told me that this sort of thing happened to him, and he had to have a M.D. remove minute pieces of brass from one of his eyes as a result----not a pretty picture, nor a pleasant experience. Far better to bush strikers properly.
