RE: How exactly do you group tune?
CargoF16
Do not pay attention to anyone that is trying to take you where you should not go at this time. "Supertune," what a bunch of bunk! I call it "thorough tuning," and it (thorough tuning) has been around since someone realized that you should tune a bow and the gear.
Cargo, just sit back and relax. When the "rads" and "zoomies" get through dumping the hype on you, there will be shooters who will come and explain to you (just) the basic tuning techniques that are required for the field. It is not that complicated unless you allow it to be.
In the meantime, if the paper-tuning reveals that you have your arrows flying straight, just adjust your sight pin(s) until you are hitting the mark from the yardage each pin is set for.
Unless you shoot often, like all through the year, it is common your groups will begin to open as the distance increases. One cause is that a pin (head) size vs. the size of area you are shooting at. The more the pin covers the spot, the harder it becomes to center and hold the pin in the same spot each shot.
Unless your hunting area requires you to take a 40-60 yard shot, which is a long shot for most shooters, why do you want/need to shoot tight groups at that distance? Determine the max distance you are willing to take a shot; tune your bow and yourself to consistently hit the mark at that distance. Put the effort where it counts.
Do not get caught up in the propaganda that you bh's are suppose to hit the same spot your fp's do, without any need to adjust. It just ain't so.
