Is shooting Prone or F-Class meant to be a "Shooting Sport" or an "Endurance Contest?" There are some shooting competitions that are a mix of the two such as Pentathlon. F-Class is a precision shooting competition. Pulling targets is a 'necessary' side effect when there is no one else to do it, but it plays a big role based on the shooters age and fitness, not to mention the quality of the puller they happen to have that match. Paid pullers are fine as long as the puller is not pulling and scoring for the person paying them. Electronic Targets are the way to go.
