are the spare set of arrows the same grain/make?
i use the same arrows that i practice with for hunting also. y not, i know they all fly good.

always shoot your bow if you get different kinds of arrows. and yes, you may need to sight it in for that arrow.

NEVER shoot your hunting broadheads into a target, unless your never going to hunt with them. keep your broadheads extreeeeemly sharp.

if i buy 6 broadheads, i will take 1 to practice with, and keep the other 5 for hunting.
