hey Long Path, I've often read recently that .257 Rbts is inaccurate. in fact, somewhere I read a comment that .257 Rbts is inherently inaccurate while .25-06 is accurate. doesn't make much sense to me.
I believe most accuracy comes from the barrel and the bullet, with other things secondary. I suppose its possible that the .257 Rbts brass may be poorly made compared to say .25-06 brass, but given the same bullet, the same effort in finding a good load, and a good rifle, how can there be a big change in accuracy?
