Mac:
I got the price of $3500 for a Merkel 140 from the Hermann's Guns site in the double rifle retailer links at the bottom of nitro forums. I don't know anything about these folks, but no matter, as even $3500 is currently well out of my ballpark. Still, a chance to dream ...
And although I hate to bring up the sore subject of the Baikal/Spartans, I see Cats has tested one over at AR in .30-06 and found it very functionally accurate. So maybe we'll eventually see a double in a useful African caliber (9.3X 74, not .45-70) for under $1,000, even if just used on paper buffalo.
