I just did it again.
I bought a really nice rifle, a Model 700 stainless fluted in .300 Savage (100th Anniversary fancy-schmantzy), unfired and mint.
Before I shot it, a local guy sold me back a really nice Model 99 in .300 that I wish I'd never sold him.
I only need one .300 Savage around, so I plan to sell the 700, but hesitate to fire it because the value will drop by a bunch.
Mind you, if it doesn't sell, I'll likely fire it and take the loss, lol.
