I'm not a fanboy of the 340, but acknowledge its place in the scheme of things. Intuitively I would shy away from one in .225 in its marginally strong enough action. On the other hand I would welcome a .225 chambered in a stout single shot, but not really enough to go out of my way for one.
The 340's claim to fame was its ability to put a decent rifle into the hands of a deer hunter or varmint shooter who couldn't afford a Winchester, Remington, or Savage 99.
I agree:
The 340 really only made sense in 222 Rem and 30-30. They wouldn't have sold any more or any less if those had been the only 2 chambers offered.
I suppose they would have had some appeal to me if I were I kid that sold newspapers all summer and wanted a shinny new new gun to hunt with that fall. There isn't anything interesting about them to me now though nor do I have any desire to own one.
Not sure we needed a live auction to discuss this point. I don't really see the live auction thing as a rule, just more of a courtesy. Either way, no skin off my nose. People can do what they want.
