The US Military spent a LOT of ammo while it was developing the .223 to try to improve accuracy, etc., the .222 Remington was far better accuracy wise. Recently some recommended the .243 replace the .223 for military rifles. That didn't get very far. But for hunters the .243 is usually a better hunting round than .223 if there is any possibility it would be used for deer or the like. The .223 is today a very good light round. There are so many .223s out there that ammo is a good deal! But I myself don't own a single .223 and will keep my .222 for my life. To many the .243. is a good light round. Personally if I had to chose between the .22-250 or the .223 I'd take the .223. But the .243 is more versatile.
However to the reloader the 6mm offers a lot!
