Unique (Oddball) calibers
I thrive on loading the odd ones: 8mm Lebel (8.3x28.5mm), 9mm Steyr
(9x23mm), 32-20 (32 WCF), 38-40 (38 WCF), and 44-40 (44 WCF) in handguns (to stay within the bounds of the original thread), however, I can't help but mention the .351 Winchester Self Loading (8.8x35mm) and .264 Winchester Magnum in rifles.
I also form the cases for the 8mm Lebel, 9mm Steyr, and .351 Winchester SL and cast or form the bullets for all the others except .264 Win. Mag.
