I have decided to build a precision/"tactical" rifle but I can't decide on what caliber. I have a rem 700sa and an AI chassis system. I do most of my shooting on my own personal range that reaches out to 370 yards. I also have a place where I can get out to around 700 yards. I also would like to have the ability to shoot 1000 yards if I ever get the opportunity. I have a lot of experience reloading and have been loading 308 for quite a few years. I am having a hard time choosing what caliber for this project. Do I stay with the 308? Or should I choose something that would be better suited for 1000 yards even though I don't know when I will ever get the chance to shoot that far? What are your opinions and/or suggestions?
