BEWARE!!
Yesterday I shot at a squirrel on a dead limb on the ground. I heard a loud SMACK!! and the result is the arrow without a point in the pic above. I believe the limb was a dried up locust limb. Hard as rock.
This evening I busted the other one stumping. It was nearly dark and I picked out what I thought was a rotten stump... turned out to be a burnt stump... again, VERY hard.
I will probably foot them with a section of aluminum arrow, check and make sure there is no damage elsewhere, and if not I'll reuse them.
Good luck and be safe.
