Like many, I read Elmer Keith's "Sixguns" years ago. I had seen references to his earlier book, "Sixgun Cartridges and Loads", but had never actually encountered one. Until I was at the flea market a few weeks ago and there it was. And it only cost me a few dollars ($3). The book is from 1936 and it is amazing how he had it all worked out back then. He tells his objectives in designing the Keith SWC, the heavy band in front of the shell case to center it in the chamber, the square grooves, etc. Even discusses his hollow-base bullets that we seldom hear much about. I didn't know that he had previously designed bullets for Belding & Mull, before the Lyman designs. The Lyman designs were improvements on the earlier ones. He also mentions that Belding & Mull made mould blocks in solid nickel. Has anyone ever seen those?
Some things you have to wonder about, he was loading the 32/20 to 1500 fps with #2400 powder, but only in the Colt SAA, since it had thick cylinder walls. He stopped using the .45 Colt because the cylinder walls are too thin, under the notches. They would bulge there and make extracting cases difficult. He says they were even know to bulge with Remington's heavy black powder loads. Which loads he did not like, with their pointed bullet. It took 10 hits with them to kill a mountain goat.
Fascinating book to read if you are interested in these things. If I can find the time, I want to try his hollow base bullets in 38.357 and 44.
