I got some 100gr tips today and I shot a little. My arrows at 40 and 50 yards flew good but at 20 and 30 yards the arrows almost seemed to have a whip or kick to them.I will shoot again in a day or two .Tonite was anoff shooting night I just couldn't keep a groupat any yardage. Would shooting the arrows without a wrap help out also or doesn't a 4.5in wrap weigh enough to matter?
