Thus Jack Lott's funny case length. The 450 Watts was available back then, along with the 450 Ackley and others. I would have selected one of the existing cartridges instead of going to all the fuss. But after all a gun writer must have projects to write about and Jack left us his legacy in a nice Dangerous Game Cartridge. I met Jack many moons ago at a gun show in San Diego, he was an up front gent that knew his stuff. Ah the good old days in California: Gun shows everywhere!
