Cannonball is dead right.
When I first read this, I thought "Over Draw".
I don't want to hi-jack your thread, but I do have a story you "might" be interested in
Back in the early days when I was shooting bows with training wheels, I had such a set up on my bow.
I could actually shoot a 19"..... dart.
"Supposedly" the thought was you could shoot a much shorter,and much lighter in weight arrow, at an increased velocity, and somewhat flatten the trajectory, and extend your accuracy range....at least that is what I thought conventional wisdom was saying at the time.
This may work, and it may work just fine, but I think it deals mostly with theory and very little with practical applications...especially with us guys with a short 28" draw.
I don't mean to be saying anything bad about the principal, as I still see overdraws on modern hunting bows, and those using them praise them highly.
But then again, they live in a world that is a wee bit different than mine.
I just can't imagine what my Muzzleloading friends would have to say if I showed up with that old outfit that I was once so proud of back then....ever heard of Tar & Feathers?
