60S has a superior SUW punch? Am we just talking about the M197 or is there something else I'm missing?Kind of what I was hinting at, these days you usually have a US MPRA for a big transit, not always but usually. That kind of reduces the advantage of the Romeo for those transits given the Sierra's superior SUW punch.
Agree that non-US MPRA tend to be useless, just about anywhere in the world.
