Mass Weight

Below is a spine weight table to give you an idea of the average, as well as the range of mass weight to be expected as a function of spine weight. This table will help you determine if Doug-fir will provide you the target total arrow mass you are looking for (for your given head weight preferences, arrow length, and spine weight needs). The weights listed below are for 32" shafts.

35-40 lb	340-380 gr
40-45 lb	350-400 gr
45-50 lb	360-410 gr
50-55 lb	370-420 gr
55-60 lb	380-430 gr
60-65 lb	400-450 gr

These are average ranges for average Doug-fir processed. We process a lot of shafts and over time we accumulate shafts that fall well outside of these ranges, so contact us if you are looking for a particularly light or heavy shafting, chances are we have it. Otherwise, simply submit your grain weight request with your order in the comments section at checkout and we will take care of you.
