After reading what stalker wrote the other day,it got me thinking about losing accuracy. I have arrows that were very accurate with poi close the same,now these arrows still shoot ok but nothing like before.i got to looking back on old post where I shot these arrows when they weren't very old. they were deadly accurate at lengths From 20-32 -1/2 inches,now neither the 20 inch,32-1/2 inch shoot like they did before. I been shooting my sons 26 inch arrow that has been shot very little an my new 32 inch ones an there's no comparing accuracy as the new ones are much better. I also found out moving to a different cock vane on the old arrowS has much more affect on the arrows than the new ones.these are small dia Carbon arrows ,but imagine the same with most carbons.i use to keep targets for groups,poi for each of my best arrows but not anymore .
