Include used rifles in your search. When I find a well made or interesting rifle then I take the cartridge it's chambered for.
If I found a really nice rifle chambered for the .280 Rem. I would buy it. That's exactly how I came to own a Sako AV in .280 Rem. I'll consider a trade with my AV .25-06. PM me if interested! 
"All that the South has ever desired was that the Union, as established by our forefathers, should be preserved, and that the government, as originally organized, should be administered in purity and truth." – Robert E. Lee
