Gentleman, I'm wanting to build a lighter weight 6-800 yard steel/hunting rifle. I would like to shoot antelope/deer and possibly a elk. I am a seasoned reloader and own numerous calibers but I'm missing a 6.5 in my collection. I'm going to use a Proof carbon barrel and manners stock but I'm torn between a Defiance tenacity for the 260AI (they don't make a mag boldface) or a Bighorn Origin for the PRC. What's everyone's experience or suggestions?
