RE: should I get the 257 Roberts?
A friend of mine had one of those and I reloaded for him. I got hooked on the caliber and in 2001 Remington made a limited run in the 700 Synthetic. I grabed one and I love it. In my mind its a much better Deer/varmit cartridge than the 6mm's. The 721 and 722 were good rifles, its probably worth the money as they are not all that common anymore.
