I agree JD. I think a proficiency and safety test should be applied to everything shooting related, then they could do away with the 12ft/lbs limit.
It's actually an overlooked law in both Chester and Hereford. In Chester it's still legal to shoot a Welshman, with a crossbow, providing it's from inside the city walls and after midnight!
Hereford, on the other hand, only observes Sunday as a closed season. You can take pot shots from Cathedral Close, at the Welsh, any other time providing it's with a bow and arrow.
