There is a good lesson there- once you discover a gun you can shoot with, never sell it. By all means buy others but never sell a gun that hits the mark - even if you don't know why it does.

The 'one gun' theory is actually sound - I remember that Clarrie Wilson, the Olympic coach, would not let his shooters handle any other gun under any circumstances. Muscle memory is a funny thing and it makes sense for those serious about winning competitions. One missewd bird costs you the medal!

I suspect many of us here share my willingness to sacrifice a little consistencty for the pleasure of shooting different old guns when the mood takes us.
