Modern Personal Defense Weapon Calibers 011: The 6x35mm KAC/TSWG, Revisited
When I started the Modern Intermediate Calibers series, I did not expect it to grow as large as it has. The initial plan was for 7 major calibers, which grew into well over 20, and the spinoff Modern Personal Defense Weapon Calibers, which itself will have at least 20 entries.
