i recently just purchased a 70 # guardian at a 29 in draw. So i upgraded my arrows to some that are 9.3 gpi. Yet my old bow was only set at 60 lbs so i have a number of old arrows at 8.4 gpi. I was wondering if it would hurt the bow just to use the lighter arrows once in a while with the guardian. Not for any large animals. Just if i wanted to fling some arrows at squirrels or what not.
