Re: 300 Ultra Mag Load
I use 90.0 grains w/180 AB. 3300+ I do have a tight neck BR chamber which drives the pressure up, hence my reduced charge. If you have a factory chamber you may need more than 90 gr. to get 3300 or better. RL25 works REAL well in a 300 RUM.
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.
