>>2466317I'm not sure but I know a bit about arrows and broadheads and stuff.
Generally they make between 100 and 300 grain broadheads. You only want to go north of 100 if you have a heavy draw. Like >50lb draw.
I listened to one of the meateater's podcasts where they got super nerdy into arrows. Generally speaking, between the time you release the arrow and the arrow hits the animal, the animal is going to move, so no matter what you shoot. Its probably going to be a good idea to have a heavy arrow as it will exert more force.
So think of it this way, you have 2 arrows. 1 is 6 grain and one is 8 grain. You are better off using the 8 grain since within 50 yards, you probably won't see the arrow dip (think bullet drop) before it hits a deer or coyote or whatever you're shooting. Its basically a little bit more weight and force kind of like if a truck hit you going 50mph instead of 40mph and can help do more damage to the animal, hence giving it a quicker and cleaner death, which is what we all want.
