Actually, I've read a bunch of stuff on a bunch of sites about the 5.7mm since this thread started, and like I said earlier I'm intrigued. Am I biased? Probably, but who isn't? Am I open to having my mind changed? Absolutely.

Yes, I've asked for input at sites like M4carbine.net where anybody can log in(no answers of any value yet, as it happens) but also a few other sites where it's not possible to log on unless you've BTDT. I'll get some good information in time, and I'll do the best I can to be as unbiased as possible as it comes in.
