Funny that they make mention of a specified length of a broadheadfor archery season but make only mention of the width for crossbows. Sounds like the hunters of OK need to petition their DNR to get that regulation changed for the bow hunters.
Archery season............
Broadheads: Hunting type points not less than 7/8 inches wide and not less than 1 1/2 inches long.
Crossbow..............
Bolts (arrows): Minimum of 14 inches in length and equipped with broadhead hunting type points not less than 7/8 inches wide.
