Well, I was thinking about using an old 22 for that purpose. For grabbing the top of a tree about to be cut down to pull it in the wind or whatever utility purpose a line throwing gun can be used for. I've run into lots of occasions where you toss a rope over something with a monkeyfist or weight on the end and it fouled.
Maybe I just need to work on my aim ;-)
I was thinking of rigging a fishing spool with some line (thanks for the correction sunray ;-)) to a projectile that could be launched with a blank. I was thinking 22 because you can get blanks at a hardware store and I wouldn't cry over boring one (or the end of one) smooth.
Wikipedia article on the 45/70 mentions the navy using a line gun in that caliber. Here's a link I found to something similar (looks like maybe a modified H&R)

I haven't had occasion to throw a line 100 yards or more, but 30 yards accurately up a tree would sure be helpful from time to time.
Heck, it would be a fun way to break into the farm house next time I forget the keys at home too - just go through the upstairs window ;-)
