[QUOTE="NikatKimber, post: 1560761, member: 423"] Ammunition / cartridges are more or less just a compromise in power vs size vs recoil vs versatility. The chemical reaction taking place inside, the metallurgy containing the reaction are what allows more power to be transmitted either total, or more efficiently, or faster; to the bullet. And to that question, a resounding NO! to the last 100yrs having been wasted. We have most definitely come a long ways in both chemistry and metallurgy in the last 100yrs. the 7x57 (and others listed) are presumably not crippled or unpopular because it fails in compromising size, power, versatility, and recoil, but rather that they were based on metallurgy that was in existence 100yrs ago. Similar to "Ruger only" loads for revolvers, or "Modern Rifle Only" .45-70 loads, that cartridge loaded to it's modern capability would exceed many of the original firearms capability to contain the pressures. And the reason it isn't popular not is just as you've said in it's favor: it's not much different than 7mm-08 in it's "old" loading; and it's close (but not quite) to what the .284 Win or 7mm Shortmags are capable of. So on both sides of the spectrum, it would be fighting against more modern cartridges that don't have the legal worries of blowing up an older gun. [/QUOTE]
