Ya got it figured Dooger....it's a generational thing. When I was growing up after THE WAR, if you saw an MM rifle it was something somebody had brought back from THE WAR. The 250-3000 and the 270 Winchester were the earlier fast stepping, light bullet catridges.
The old MM stuff usually had fast twist barrels to stabilize the extremely long bullets used then and once again the rage for ultra-long-range shooting. There wasn't much out there for fast twist 270s and the longest bullet common was the 160NP, IIRC.
The young metro-sexuals hanging around here think they are on the cutting edge with their metric stuff while the Geezers continue pile em up with 270s.
