There is a time, in years past, that I would be all over the latest new caliber. Examples in the past like the .460 G&A, .450 Marlin, and .338-06 in rifles, and .357 Sig in pistols. These days, with the availability of so many great bullets, I think the allure of the special caliber is basically gone. In rifles, all the similar calibers kill game well, assuming a well placed shot and appropriate bullet weight, good bullet construction and appropriate external ballistics. Same thing has happened with service pistols and calibers. New calibers today are mostly great at selling new guns.
