So I've been thinking hard about a 260 Rem barrel for my 308 FP10, and I run across the 6.5 MPC which is a blown out 223. Good with 120 gr SMK's, which would of course work OK with 260 Rem as well.

Unfortunately, there is a lot of loud clash, crash & bang out on the intertubes about this round. Anyone play with it? I searched "6.5 MPC" and got no results here.
