For all around fun that I get a rise out of every single darned time that would be the gun that my dad gave me for my 12th birthday that was my great grandfathers. A Winchester mdl 67A single shot bolt action rifle. I have several others that I love to shoot, and my Marlin 44 1894 levergun is right up there, but the ole single shot 22 is just dead nuts accurate and cannot be beat for shear enjoyement. Plus it doesnt leave me sore when I am done shooting lol. And you will have to excuse the mess, I am still working on getting a desk to mount all the reloading equipment to lol.
