RE: NAP Thunderhead
I agree.... Thousands of bowhunters use NAP Thunderheads. They work, plain and simple.
BUT - in my experience, they are just a tad heavier than they are listed at. 100gr is actually 106. 125 is actually 130. Then again, 5-6 grains is not enough to really cause concern. Out of a perfectly tuned bow, they will fly accurate like a guided missle. But then at longer distances, 40-50 yds... you may want to aim just an eyelash higher.
