Nice, I love to hear about double rifles. I have to admit - I prefer the side by sides.
As a small child I had an old Daisy double barrelled BB gun - it actually belonged to my uncle. It gave me quite an advantage in our BB gun "wars". Paired with my green walnut slingshot - powered by an old inner tube - I could easily hold off a charge from my tree fort.
Football helmet, goggles, shirts and pants stuffed with magazines and newspaper - it was game on.
Kids today have no idea what they're missing.
When I got a bit older my dad outfitted me with an old Iver Johnson single shot, break action 20 gauge and introduced me to pheasants, dove, and quail.
Longing for a double, I located an LC Smith amongst my dad's collection and asked if I could have it. His response was, "If you can handle it - you can shoot it". I shot that LC until he suggested I switch to one of his Berettas. I still shoot Beretta doubles.
There was a Heym 375H&H double for sale awhile back, based on what I'm reading, perhaps I should consider it or maybe something even smaller - sounds like fun.
