Here is some information from a 2001 ODFW report I found on their website. (search mechanical broadheads)
Mechanical Broadheads, Concerns include: o Generally reduced penetration compared to fixed blade broadheads.
o Require more power, not suited for the lower draw weight bows many hunters including some women and youth use.
o Wide variation in effectiveness; some are very good, some very poor resulting in breaking and/or poor blood trails.
o Once opened they are “barbed” so more inclined to remain in animal.
o Encourage long shots because they “shoot like a field point” which are generally more accurate than fixed blade broadheads at long range.
Because mechanical broadheads require more energy their effectiveness is reduced at longer range, where they may have an accuracy advantage.
o High quality effective fixed blade broadheads are available resulting in no strong need to allow the use of mechanical broadheads.
• Overall, the group was concerned about the poor image many people have of bowhunters this image is contributed to by animals “running around with arrows stuck in them, stories (particularly of wounding, loss) they tell in public places, and “poor taste” videos.
o The perception that hunters are shooting too far could be heightened by the use of rangefinders, mechanical broadheads and other equipment that could encourage hunters to take longer shots.
I believe these comments may have come from a Wildlife Commission meeting. ODFW does not make the law. Your legislature does.
A quote from the website, "Commissioners formulate general state programs and policies concerning management and conservation of fish and wildlife resources and establishes seasons, methods and bag limits for recreational and commercial take"
SOOO, if you don't like the law YOU can try to change it through the proper process.
iHunt - I'll bet the idiots you speak of have decent grammar, punctuation.
