I have been shooting a Cobra pendulum on my bows for the last few years. I normaly sight them in on the ground at 20 yds and am good to go to about 30 yds. After that they start dropping off. The guy at the bowshop said I should try an Impact Archery pendulum as that gave him out to about 45 yrds. My question is, does this pendulum give you that much more distance? Does any brand pendulum give you this kind of distance? Or is there a different technique I should use in setting up the sight? My bow is shooting around 300fps.
