G'day im james and i live in Australia, most of you are from the US i take it. Theres not asmuch deer here in Oz but i live about one hour and a half away from a few properties that have deer on them over 6000 acres. Im going up there in a few months. I've got a newbie question, is it advised to use an arrow that has a lesser poundage weighting on a higher poundage bow?

cheers,james

welcome man! It's not advised to do that, but try it and see if it works for you. I try to use my 55/75 arrows at my pull weight of 61#'s.

does it affect the bows lifespan or cause its limbs to crack?

thanx

Barney, Welcome.

A rule of thumb: 5 grains of arrow mass for every pound of draw weight. For example, if you're shooting 60 Pounds, you'll need a 300 grain arrow. Anything less can cause damage to your bow. Arrows are splined for a distinct draw weight (spline = an arrow's resistance to bending). It is not advised to shoot a light splined arrow through a heavier bow. I have seen people injuried (parts of arrows through hands, etc). Make sure your arrows matches your bow and vise versa.

Best of luck hunting!

Repeatedly , it can cause problems, but immediately it will be inaccurate due to overflexing and not enough time to compensate before impact. Itis crucial to match the arrow spine to the weight of your bow.
