Re: .257 Weatherby Mag
I have had one for over twenty years. And I agree a 6.5 caliber will take you out to 1k much better. But for a quarter bore, it does the job. I have been shooting barnes 100gr bullets out of it for some years now. In my experience with the 257 I have had no issues when a good hit was made. Please let me be clear, I have only had the opportunity to stretch this gun out to a distance of 500 when hunting. 100gr barnes ttsx's I have gotten very good groups with, at just under 3800fps. RE 22, and MAGPRO are the powders of choice in my MarkV.
