For those that may not know the "Troyer" scale is used to determine the difficulty of any given Filed Target match (at least in the US). This gives you the ability to compare difficulty of various matchs across America. Created by Brad Troyer who happens to be not only an excellent shot but one heck of a nice person who has done a great deal for not only Field Target but airgunning in general. It is well worth checking out his site which he started in 1995 not only for field target information a great deal of information regarding airguns. Brad's site:
