I picked up a pre 64 win action that was a 30/06 and I am going to have a gun built but can't decided what caliber. It will be for deer to (elk If I ever go). I wanted to go with the 257 weatherby but the 264 win keeps coming up but although i own a stock win with a 24" barrel I think it could be better with a 26" and some hand loads. i don't understand after reading most of my reloading manuals why with the extra powder why the 264 only duplicates the 270 win MV. I am still leaning to the 257 but I think the 264 will buck the wind better... This is my first custom gun and run at a somewhat longrange shooter.. any input would be great .. Thanks
