Guys,
I find this thread very informative. I am new to the trad bow only been shooting 2 years. I shoot 3 under, and just recently fought with tuning bare shafts. Now I'm no pro at shooting, but I like challenges, so I try to stay at things till I get them just right, but with the bow I have seems like I hit a road block in tuning. The tail always stays a hair up bare shaft(about 1 inch at best). I moved the nock point from 1.25" to just under even to see how to get that tail down and results would get worse as soon as I left the 1/4 to 1/2 area. I also, increased the brace height with some advice from here, and it dropped the tail high from 4'' to the 1'' high spot.
Now, with fletching they are barely noticable tail high. And strange, from elevated shooting they drive right in straight. I thought it may be because I have what I consider a bottom of the line entry level bow(martin x150) new it only runs about $220. I have a friend with a black widow he is going to let me shoot once we can get together. I'm guessing another bow may more forgiving for my inconsistent form, but even with the martin i am finally getting arrows to group up 2-3 inches at 10 yards, which makes me feel better.
thanks, david
