Garrett tested a bunch of different arrow weights from under 400 grains to over 1100 grains and then analyzed the speed, kinetic energy, and momentum.
Garrett tested a bunch of different arrow weights from under 400 grains to over 1100 grains and then analyzed the speed, kinetic energy, and momentum. Often there’s a fair amount of debate for which metrics are most important when it comes to choosing a hunting arrow. In this podcast, Garrett and Bobby discuss why they think momentum is the more important metric than kinetic energy when it comes to penetration (although kinetic energy certainly isn’t worthless) and they discuss the results of the testing. Spoiler alert, momentum increased with higher weights… a lot. And it showed no signs of slowing down.
It’s important to remember that momentum is just one factor to look at when choosing a setup for hunting. Speed (trajectory), arrow flight, shot placement, broadhead style, and the animal you’re shooting at, all play into the equation. This podcast does get pretty technical, but it does have some no-nonsense takeaways for even the typical whitetail hunter.
