[QUOTE="DJ Fergus, post: 1834322, member: 93895"] I'm not sure that I always buy the efficiency bit thats dubbed on certain cartridges. Maybe sometimes a certain cartridge works better with a certain barrel length and certain powder than others do and we make claims to it's efficiency. We could probably burn n570 in a 28 nosler with a 30 inch barrel & drive a 180 grain to nearly max pressure get close to 3400fps and make claim to it's efficiency but not many folks want to run a 30" barrel. Case capacities of of certain cartridges of certain caliber sizes seems to get us desired velocities in popular barrel lengths and there's no doubt that when it all works together like that it's certainly a great thing. I guess thats when we decide it's very efficient and the ultra sized cases seems inefficient but I've got to ask myself the question of how efficient the ultra sized cartridges would appear to be with optimum barrel length for that cartridge.
