Speed and trajectory
I was out tinkering and increased my draw weight by @2 lbs. (60 to @62). At 60 I was shooting consistent groups out to 40 yards(my limit). After increasing the draw weight, I kept the groups but they dropped @12" from my aiming point. I know the trajectory would be a little flatter but would it be that much or does it depend on the set up? I am shooting a 2002 Cybertec, Versacam 2, 28" Draw, TT rest, Beman ICS 400' s at 27" , with Sweet Spot release. Any knowledge of this would be appreciated. Thanks Chris

RE: Speed and trajectory
Are you sure that your sight didn' t move? Possibly your peep slid down a bit?
I have an 03 Razortec and occasionally move around my draw length 60, 62, 65, and have only a very minimal change in my point of impact. 12" sounds like something moved.

I have to agree with Redline. Add 2# and you ain' t gonna see squat for change unless you can shoot 60 yards or more. And even at that you' ll only see a couple inches at best. Something else changed.

]If the site didn' t move, then my guess would be your peep moved a bit or your nocking point moved up.
Something had to change

RE: Speed and trajectory
Yeah something isn' t right.You may have a tiller problem but even that doesn' t sound right.I agree that something moved.
I changed my draw length down 1/2" and went from 273 fps to 266 fps. The difference showed up @ 60 yards and I was using my 62 yard marking on my sight tape to hit dead on @ 60.There may have been about a 1 yard difference at 50 but I went from 40 yards to 60 without shooting 50.

RE: Speed and trajectory
well, i moved my draw weight back to 60 and made sure everything was still in place. I shot 4 arrows just to check my sights at 20 yards. All 4 were within 1" of each other. I thought something had moved to but nothing did. Same measurements as before. Thanks for the thoughts though.Chris

RE: Speed and trajectory
Fastpassthrough,that is what I was thinking when I stated that the tiller may be off,but 12" is quite a bit.I have never experienced that kind of a change regardless of what I did to a bow.
I also think that he should try it again and see what the result might be.
