Previous to Hatcher’s Notebook is Major Earl Naramore’s 1937 Book Handloading.
http://www.castpics.net/subsite2/Cla...20- 1943.pdf . In the 1920’s , Major Naramore is a frequent contributor to Arms and the Man. He is a true expert ballistician, a truthful man, and I expect his 1937 book was written close to or after his retirement. And this is what Major Naramore says about the tin can ammunition:
"Page 159
The ammunition made a Frankford Arsenal for the 1921 National Matches had bullets heavily plated with tin. This ammunition was satisfactory when first loaded. Tin has an affinity for brass and in this ammunition the tin combined with the insides of the case necks, forming a union between the bullet and the case just as though the bullets were soldered in place. This union is so strong that it is impossible to extract the bullets and if the ammunition is fired, dangerous pressures will develop. Most of this lot of ammunition, the only one so loaded, has been shot or destroyed, but anyone running across any of it should destroy it or preserve it only as a curiosity in the development of ammunition It should under no circumstances be fired. The marking on the case heads is, F.A. 21-R"
