Arrow Weight Difference by Manufacturer
This is a basic bar graph that shows the average weight difference for each company and compares it with the other companies. Other than the Element Archery results, most manufacturers have tight weight standards.
On a 400gr. arrow, a shaft weight difference between Easton arrows at 0.4 of a grain and Carbon Tech arrows at 1.3 grains difference is not enough to make you miss your game at pretty much any distance.
the Element arrows however, represent almost a 2% difference. On a 400gr. arrow that's a 7.6 grain difference which personally I feel is too much. I probably wouldn't shoot these arrows past about 20 yards or so.
