The big 7s.That's what I'm talking about.I am just a country ass 7mm fan just like I enjoy my .25.I know a little about the .308 as I became very intimate with it while in the military.If there is a 7 out there that will give you 4000 with a 140.I don't need to look any farther.I think the Laz will do a 4 grand .30 cal. 150 wont it?Need to find a new smith anyway if anybody remembers my bud that started building the STWs around here died from some of those little nastys that everybody brought back from across the pond.
