For my build I have narrowed calibers to 7 saum, 6.5 PRC and .284. I shoot to 600 yds but hunting will be limited to 400 probably. Mostly whitetail hunting but go west on occasion. I am a hand loader and a 7mm fan but hear good about the 6.5 PRC. Would like to stay with a short action. I would appreciate your input. Thanks Barry
