Hi Guys I have been shooting Olympic recurve for a couple of years. Lately when I change from indoor 18m to outdoor 70m I have had to do 7 full turns of my sight pin to get the shots centred. Assuming the sight is fitted and set up correctly and my form is consistant what else could be causing this? I have asked more experienced Archers at my club and was told it was the tune. But nothing more specific than that. Any and all help much appreciated, thanks in advance.
