Re: Fire-forming reduced loads for RUM
90.0-95.0 grains of H50BMG under 178 AMAX's in the 300 RUM are good accurate mild loads.
If sized properly, you sure can get more than 3 firings from an RUM case.
Long range shooting is a process that ends with a result. Once you start to focus on the result (where the shot goes, how big the group is, 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.
