RE: Help
The 280 rule is for the short draw archers.It is a safety rule that allows them to go under the 5 grain rule as long as they stay at or under 280 fps.
You can NOT use a moveable sight in the hunter class.You would have to step back and shoot from the open stake,which would not be advisable as a beginner.
BUT,you can go and have fun with your equipment and just tell them that you are not competing.Just shooting for fun.
