For the first time today I was able to accurately weigh my arrows (Beamon Venture 340's with 100 grain tips). They weighed 429 grains! My bow (Hoyt PowerTec set at 28 1/2 inch draw and 67#) shoots 255fps with these arrows which gives me about 62ft-lbs of kenetic energy.

So, here is my question - Should I be concerned that my arrows are so heavy? It really surprised me that they weighed so much. Should I try to get the arrows down around the 350-390 range or does it not really matter?

I will be hunting elk and I know that longer shots are a possibility so I need as much speed as possible, but I cannot forget about kenetic energy.

Any suggestions would be appreciated.
