This cartridge is like the one discussed in IAA#461 (May/June 2008) “The Case for a .400 Belted Whelen” by John Pople-Crump. The bullet is gilding metal with a small hollow point as looks like the Western Tool & Copper ones loaded in the 350 G&H Magnum. It the article it stated: “Whelen Experimental Cases Made from Hollands .375″ Magnum Belted Cases”. This cartridge was originally labeled as a 404 Hofmann from the Peter Skala collection.
