A couple on the political side:
1. "Safeguarding Liberty - The Constitution and Citizen Militias", Larry Pratt, editor. 1995 Legacy Communications, Franklin, Tennessee. ISBN 1-880692-18-X. Has some good, well-reasoned stuff by David Hardy and David Kopel, inter alia. The Appendix has the complete text of the Militia Act of 1792, only superceded about 100 years ago. (SOME WHO WERE ALIVE THEN ARE STILL WALKING AROUND!) One of the articles most conclusively proves (speeches in Congress, quotes from the Founders, etc) that the Nat'l Guard is NOT the militia!
2. Poe, Richard, "The Seven Myths of Gun Control - Reclaiming the Truth about Guns, Crime, and the Second Amendment" 2001, FORUM, An Imprint of Prima Publishing, Roseville, California. ISBN 0-7615-2558-0. Read the Epilogue first. Its title is "The End of Manhood". Ouch!
On a lighter note: Oh, yes, I most heartily and enthusiastically recommend "Cartridges of the World". My copy of the 7th edition is falling to pieces; I often fall asleep over it, or contemplate it in the "library" while doing my duty. I WANT a rifle chambered in .219 Improved Zipper, just for the silly name!
