Interesting stuff.
Some links I found in trying to learn more:
http://www.i-kirk.info/misc/quickkill/qwikill.htm
http://en.wikipedia.org/wiki/Lucky_McDaniel
http://www.pointshooting.com/1aqkrif.htm
The books I could find on Lucky McDaniel are all out of print and bringing quite high prices used on eBay and Amazon.
I have a slide action BB rifle. The action is a little sloppy, but IMHO, it is quicker and easier than the lever action.
I’m open to arguments, or instructions, except where to put it.
