Well I'm not gonna play this caliber vs cartridge, AD vs. ND, clip vs. magazine, or the "a revolver isn't a pistol" game. Just petty....
For my needs we're talking either a .243 or .260. Maybe throw in the 6.5 Swede, the 6.5 creedmore, the .250 Savage or a .257 bob. Because of population I need a caliber (Sorry, CARTRIDGE!) that has available very fragile varmint bullets as to keep ricochetes to a minimum but also has good, quality game bullets for larger game. I also need a good amount of range and accuracy.
Any of the above listed rounds will do everything I need and then some. Don't need bigger and smaller won't do everything I need. As for the police aspect of the OP's question I have no input except to say that any of the rounds are more than big enough and accurate enough for law enforcment work at any level.

BTW, if it wasn't for population, predators and varmints the 7mm-08 is prehaps the best choice. Just not for me in my area.
