Now the SAW cartridge I do like, at least the concept of it, but it does push the weapon size envelope for an assault rifle.

Yes, a little. But, nowhere near as much as Murray's 7mm UIAC. Although from a technical standpoint the 7x46 offers a slight advantage over 7.62x51, I think he's going down the wrong track.

The Chinese have basically adopted that cartridge with the 5.8x42 in their QBZ95, LMG, and DMR. I've heard they're not happy with its downrange performance at distance though, but who really knows...

They made the mistake of not going quite big enough. 6mm is the minimum necessary for long range, 6.35mm might've been the best, considering the trade-offs for minimum cartridge size and weight, and acceptable ballistics.
