Re: 1000+ yd. 30 Cal. bullet weights
Alot would depend on velocity ect...
I feel that if driven fast enough and as frail as the 155 AMAX is the 155 AMAX could be a contender. Otherwise something along the 200 Accubond would be my favoriate choice.
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.
