EXTREMELY DANGEROUS .41 SPECIAL LOADS

I just received the latest 2019 Edition of Cartridges of the World. It has the .41 Special listed under Wildcat Cartridges with the same information as previous editions. These loads are safe. HOWEVER, it is also listed in the Handgun Cartridges section with extremely dangerous loading information. One load listed is a 170 grain bullet over 12 grains of Red Dot!!!!!! at 250 feet FPS faster than the same bullet in a .41 Magnum. I would expect this load to take a nice custom .41 Special sixgun apart. BEWARE!
