Chief - I bought a H&R 10 guage, with 36\" full barrel back in the late 80's.
I thought I would use it for fox calling and crow calling...
But man that 36\" barrel was just too heavy. I could not swing it on something like a crow flying over. And it was too heavy to hold up long at all - like when you are trying to wait out a turkey that is coming in.
I have seen them made for turkey hunting with the shorter barrels and I am sure that would work much better.
Probably kicks like a mule though.
