I used to shoot competition, and in fact shot for a living for awhile.
Have no interest now in doing shooting for any reason other than I "want to" or need to.
I did shoot a regional match with rifles and handguns for a few years, but have not even done that for 7 or 8 years now. No interest.
Not reading through 27 pages of that link... Did you show 'em how it was done?
