I am trying to play nice. I guess I was reading guys minds. I am not sure how anyone who knows anything about rifles would somehow get 6.5 creedmoor, 6.5 anything out of the post that reads 6.5 Weatherby. You can make the cartridge out of 257, 270 or 300 wby brass. And just to clairfy Weatherby is making factory brass and ammo now.
Regarding the last sentence in your post, this is a cartridge I am genuinely interested in pursuing. Are you saying Weatherby is offering 6.5/257 brass?
