I've been shooting the smallbore and cowboy lever action NRA silhouette matches for about a year and a half now. After seeing a few other guys shooting their Contenders at our smallbore and pistol cartridge lever gun matches, I've decided I want to try it. I have a standard factory Contender in 22lr with the 10" barrel and want to set it up to shoot the match. I can't find the rules pamphlet anywhere online, though, and want to make sure I am doing everything by the book (weight, lengths, etc.). Any help out there?
