here's the deal. I had my bow shooting great, broadheads and fieldtips together just fine. Arrosw appeared to be flying straight and all that good stuff. so then I get bored (bad idea) and start reading about center shot and all that. hmmm so for some reason I think "you should paper tune." ok, well the first shot from about 6 ft. has a 2 inch tear high and to the right. so i start adjusting and shooting and adjusting more. I did this for 2 hours (unsuccessfully) and stopped before I got too mad and did something stupid. So needless to say I never did get any bullet holes. And now the whole thing is probably all out of whack. Looks like I get to start all over again. WHY oh why did I do this??? And any idea as to why everything was shooting so well and then when I paper tune it will darn near tear a 8.5x11 in half? thanks everyone.
