OK. Some new information has come to light which changes the arguments slightly.
From the BBC website.

Blind hunters are not a new phenomenon in Texas.
Under current procedures, a sighted guide can assist a visually-impaired hunter by peering over the hunter's shoulders and advising where to aim the gun and when to pull the trigger.
However, hunters say that without a laser pointer it is difficult to time the shot.
So what this bill does is it allows modifications to the existing legislation to allow blind hunters, who already can hunt blind, to make them more accurate. That deals with the issue of accuracy that JackDog brings up, as it's an improvement on the current status.
As for accuracy of other things, whilst I appreciate that a truly skilled bowman or black powder marksman can be more accurate than the average bloke with a rifle (Well, for a bow, at any rate, I'm not sure about the black powder), I don't think the numbers of people who make it to that level of skill truly are enough to counterweight the inherent inaccuarcy of those systems.
