Very nice! I could go for a AR rifle in that caliber.
Found an article touting the usefulness of the .243 as a service round.

Weight reduction and reliability, performance and a 1000 yard max effective range, common caliber for a squad automatic weapon.....whats not to like....:o)
I love the 243 .....
Stay Safe , thanks for the link.
Trying hard to remember, but i think the Brits wanted something like that rather than the 5.56 but the US steamrolled them with the tiny cartridge. Might not have been .243, but was bigger than .223.
I always thought that for a combination of weight and punch, the .250 Savage would be a decent service round. The commercial loadings don't take full advantage of the cartridge and are watered down a bit to accommodate some of the older model Savage 99s floating around out there, but with a higher pressured loading it would make a nice replacement for the 5.56.
