1.) A: .44 Magnum (although the movie was filmed with a .41 Magnum). Tokarev is a snappy round but not really a magnum. The .32-20 WCF’s superior penetration was praised by Robert Johnson in his song, .32-20 Blues.
2.) C: Belts, reliably allowing the round to headspace at the rear of the chamber. Brass alloys have come a long way since contraction led to the naval term, “cold enough to freeze the balls off a brass monkey.” (Browning solved this problem by designing the .50 BMG M-2 with adjustable headspacing.)
3.) C: Short Magnums. Short, fat chambers allow less powder to do the same work with less recoil—and in a shorter action. Some say the trade-off is less-reliable feeding.
4.) C: Express. The terms, “Nitro” (for smokeless powder) and “Magnum” (based on large champagne bottles), appeared later.
5.) D: .375 H&H. Powerful enough for dangerous game, and with a tapered case for flawless chambering and extraction, it’s still more popular than newer cases (such as the excellent .375 Ruger and the once-and-future .458 Win. Mag.). The 9.3x72R is a rimmed black-powder round.
6.) A: .460 S&W. S&W did the same setup with its .500 revolver, designed for campers and fishermen. Nambu? Don’t be silly! The Casull and Ruger are both hard-hitting revolver rounds.
7.) C: .224 Weatherby. This confection is more of novelty than anything. The other rounds are vintage rimmed, bottleneck varmint rounds.
8.) B: .338 Lapua. Navy developers in Crane, Illinois, teamed with Finland’s Lapua, which used the rimless .404 case to create the finest long-range rifle cartridge of our time. The other cartridges have proven successful over time. The Winchester and Weatherby are full length and belted, while the Steyr is based on a shortened 9.3 Brenneke.
9.) A: Longer … for now. The voodoo-science of priming offers developments every few hours, and you never know what marvels will come out of Hornady’s lab, so this answer could be inaccurate, even as it is being written.
10.) D: .357 Magnum. This fabulous revolver cartridge became the standard of American lawmen until it was phased out by semiautomatics in the 1980s after the infamous Miami Shootout. The other successful cartridges are from other decades.
