Nooooo, no T-Rex thumper for me. When I was young I liked magnum handguns and standard cartridge rifles. As I continued getting older and older, I flipped, liking gentle handguns and magnum rifles. The S&W 500s would cripple my arthritic hands.
I fired a Taurus Judge not long ago and that was extreme - for me. I would like to fire a 500 mag, but I do not think the FFL's around where I live - MD - have one to test.
There is a cool video on youtube featuring F. Lee Emry comparing a M16 and an AK 47 - single round power, disassembly and assembly, and accuracy at full auto.
