Re: ballistics of 7mm-08 & 6.5x284
IMHO, they can be dam? near equal at 1k. Comparing bullet type against type such as the 6.5 140 Amax versus the 7mm 162 Amax driven to max potential, they're within just a few inches of wind and have nearly the same energy at 1k. The 7-08 however will always leave a bigger hole with twice the barrel life.
Long range shooting is a process that ends with a result. Once you start to focus on the result (how bad your last shot was, how big the group is going to be, what your buck will score, what your match score is, what place you are in...) then you loose the capacity to focus on the process.
