I don' t know what shop you WON' T find .22-250 ammunition in, every single one I' ve ever been in has it in more than three makes, let alone weights per maker! I much prefer the .22-250, flatter shooting, and don' t let them fool you, it is noticeable, especially when you use the round to its full potential.

Yes, .223 has very available surplus ammo, and it is very crappy, it' s very cheap, and still not worth the money in a gun that a guy would spend that much money on, i.e. a target/varminting rifle or a M-16knockoff. Like that commercial with the new car, chevy of some sort, and the pump man says, ' so, the super plus right?' the guy says' nah, just the super' s fine,' pumper ' really, the super?' If you put crap in your gun, you should expect it to go to crap. You get what you pay for. It' s often FMJ as well if it isn' t steel cased and berdan primed to boot, terrible for reloading, and illegal for hunting.

Remember some things when you compare yourself to the military, you don' t carry a gun to save your arse everyday, you don' t have to carry lots of ammunition to make sure your gun can save your arse, you want to kill what you hit the first time, whereas they want to wound men to draw others out to fetch him, one good shot can equal fifty dead men, you want to hit a gopher/groundhog/coyote at 400yrds consistantly, they want to hit people at under 200yrds. They switched from the .308 to the .223 (NATO rounds of course) because the 22cal is a better ' wound em' round, and because they can carry almost twice the ammunition in the same weight, and still get virtually the same effect in the battlefield.
