Haha, I use a crank. A few pulls ain't so bad, after 20 or so you gotta have a crank. When you see them in action you will be surprised. The range near where I live won't allow them because they said the insurance for it is to high. When I asked why, they told me they tested some and the bolts penetrated their walls. They had two walls of phonebooks and hay bales? in front, its a good thing they have brick behind that or they would have been in trouble!
