I have a winner
I finally made a dozen arrows for shooting with my 55# limbs. This is going to work great! My Hunter shoots 1916 arrows, 458gr. at 172 fps. The same bow with the 55# limbs shooting 556 gr. arrrows is producing 172fps. Both are a 5 arrow average. The way I have it figured, I can shoot the 45# limbs for 3-D and switch to the 55# limbs for hunting and have the same trajectory for both. No re-learning for hunting season. I like it! The cast should be the same. <img src=icon_smile_big.gif border=0 align=middle><img src=icon_smile_big.gif border=0 align=middle> Dick
