I'd grab what you can get at this point. With that said, my 22-250 and 243AI seem to do better with WW but my 308 does equally well with WW or Remington, can't really tell a life difference with it. I just bought some Remington 270 WSM brass for my 6mm WSM and it seems to be very decent but can't attest to life at this point. If I have the option I ussually buy WW, but really have nothing against Rem at this point.

I suppose what turned me off of Remington Brass was the first thing I had loaded with it was 44 Magnum and I noticed a lot of variance in the rim diameter and thickness. The WW brass for the 44 Mag was much better. I suppose my preference for WW spawned from that, but I'm giving it a 2nd look out of necessity.
