Again, an answer to a question nobody serious asked. As with cartridges like the.45 GAP, .40 S&W and .327 Fed, a passing fad with nothing new ballistically nor any sort of superiority in any category to supplant anything that's been around for the past hundred years or more. The cartridges I mention above all have their "ancient" and "outdated" equals- .45 Schofield, .38-40 and .32 H&R mag. Personally, I'd like to see, as with Dick Cassull's duplex loads, something on that order applied to cartridges such as the .38 Super, .45 ACP and 9mm to boost their performance in strengthened platforms.
