Sixty yards is the regulation distance between shooter and target. The rules are generally simple. You can use any rifle of any weight and of any caliber provided that it has fixed open sights. False muzzles are not allowed, and many matches restrict the rifles used to those of a traditional style. Shaders are allowed over the open sights at the Friendship matches and at most other matches.
Percussion ignition seems to be favored by most chunk shooters.
Scoring is based on a string measure of one or more shots. Two record matches and a weekly reentry match are available on the Walter Cline Range. On Wednesdays the Bill Large Match is fired on the Primitive Range. The Bill Large is a reentry match which is fired all day long on an informal basis. Relays are timed on an irregular format, and vary from fifteen to thirty minutes, depending on who is shooting and how many are waiting.
