.243 is a great round and I would love to see the troops reaction to the extra reach-out-and-touchability.

I agree the .243 would be a killing round.

I also wonder if the old 6mm Lee Navy round could be resurrected. With modern powder and rifles it would be really deadly. It had a reputation for accuracy too.

The only downside is the .243 would be only marginally lighter than a 7.62 since they use the same case.

I believe the perfect battle rifle cartridge was developen around 1894, the 6.5X55, which was chambered in the Norwegian Krag and Swedish Mausers.
