RE: How exactly do you group tune?
<BLOCKQUOTE id=quote<font size=1 face='Verdana, Arial, Helvetica' id=quote>quote:<hr height=1 noshade id=quote>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.<hr height=1 noshade id=quote></BLOCKQUOTE id=quote></font id=quote><font face='Verdana, Arial, Helvetica' size=2 id=quote>
Huh? What kind of logic is this? Why limit yourself to practicing at just your max hunting distance?
If you can tighten up your groups out to 80+yds, and practice long distance shooting, it makes those 20-30yd hunting shots look like cake. Take up field spot shooting for a while- it'll open your eyes quite a bit. There's nothing like shooting a great group on the 80yd target!
As far as the tuning process you asked about- I do things very similar to PW12. But I seperate the X and Y axis into two different procedures. I'll concentrate on the Y (vertical) axis first with VERY small incremental adjustments in my centershot position. All I'm watching is my horizontal spread as I'm shooting at a vertical line with each adjustment- is the spread getting bigger or smaller? If it's getting smaller, I keep incrementing the centershot in that direction until the spread starts to get bigger again. I make notes as I go along, so I look back and see where I had the smallest horizontal spread. Then I know I've found the optimum centershot.
Then I move onto the X (horizontal) adjustments with nock point and repeat the above process until I've determined my optimum nock point position.
If I'm not satisfied with my results, you may have to consider a tweak in the arrow spine/bow combination. Maybe I'll give the limb bolts a crank up or down depending on how I think my arrow is behaving and repeat the entire procedure. Maybe I'll cut a 1/2" off my arrows that I intentionally left a tad long just for the "tinkering" purpose, and then repeat the entire procedure. Different tip weight, and repeat the entire process...
You can get as "anal" as you want with all the variables in the mix, and at some point you'll have to say "this is good enough for me". The most important thing is to have fun and enjoy what you're doing!
