Ok guys, got kinda a odd deal here. First off, I'm shooting a Bowtech Guardian, 29" draw, 67 pounds and Easton FMJ's (267 fps). I have a HHA Optimizer or whatever, pendulum sight. It has those stupid stickers that you put on with the preset ranges. I thought I had the right one but....now I have a problem. I am DEAD on at 20, 25, 30, and 35 yards. I mean like right on, no doubt about it. But, when I go to shoot at 40 I am like 8 inches low!! How can this be with a difference of just 5 yards? Could it be because I'm shooting such a heavy arrow? Any help appreciated!

Sorry, tried to edit

I'm real dumb, did the same thing again......

It seems odd your Guardian would drop that much in 5 yds. I have the General, 26.5" draw, 67lbs, shooting a 438gr arrow. Mine does notdrop like that until I get back to 50yds. Back to 40yds its good. So I guess depends on how heavy arrow you are shooting.

the hha sights and sight tapes are designed to be sighted in at 20 and 60 yards. then you will be on at all ranges i think. im pretty sure thats how it works though. can anyone else help out.

Yeah thats how I did it. Can anyone explain this? Its probably just something I did, but it makes no sense at all.

Don't make sense, I'd get a new tape and try again. You can get a BLANK tape, and mark it yourself, that may serve you better, but you shouldn't have had THAT much drop in such a short distance, something's not RIGHT there.
