Temperature
Does temperature affect a bows velocity? I notice that when I practice when it's real warm out my arrows tend to hit a bit low. Is there less snap to the limbs when they are warm? Another question.I shoot a Bowtech Pro 40 dually. My birth certificate says 321 fps at 29" (70 lbs) I have changed modules to 28" to accomodate a string loop. My arrows are 400 grains. What kind of velocity should I be getting? I don't have a chronograph.

RE: Temperature
I'm not an expert by any means, but I had asimilar problem last fall. Arrowsweren't grouping well as the temperature fell. After re-tuning the bow and contacting PSE, I realized thatI was the cause ofthe problem, not the bow.
As the temperature dropped,I tended to be a little stiffer in my stance,causing the loose groups. After understanding what was going on, I was able to correct the problem.
Maybe in the warm weather you arechanging your formor shifting your anchor point?Hope you can fix the problem.

RE: Temperature
I would think that air density would change things a bit. I mean, let's talk baseball a second. Coors Field in CO has homers knocked out of there all the time because the air is thinner. I can't see why the same priciple couldn't be applied to arrows. More humidity = more wind resistance.
