Actually, if you're going to buy loaded cases for ten dollars more than empty ones only to pull the bullets and reload them, then I think you're the crazy one.
I bought a box of Weatherby ammo so that I could fire some of them through my .300 and compare factory loads to handloads, but that's the only reason why I'd do it again.
I bought Hornady brass first because it was cheaper. I think it's also a little softer and have since purchased Weatherby brass. I found that the Hornady brass has a lower case capacity and got similar velocity/pressure readings as the Wby brass did with 2 grains less powder.
