I'm getting ready for another build to start in a month. I've narrowed it down to these to calibers I think. From what I can tell they are pretty much identical. I'm using a long action. I would like to shoot 100-120gr bullets out of it. Just another thought would it be worth the hassle and extra expense to to with a 260AI. What Twist for the 2 calibers. Which would you choose base on brass, accuracy and volicity. It'll be for whitetail and paper punching.
