[QUOTE="Greyfox, post: 1288540, member: 10291"] [b]Re: Suggestions for Reloading Excellence?,[/b] IMO, the load development process(design) is a prerequisite that defines reloading excellence. The requirement of a +1000 yard long range hunting is more demanding then even Benchrest competition. The variables and demands for the LRH rifle/load are far more. Establishing consistency in the process/components of the reload is the easiest part, once the load is designed. The "excellence" part,IMO, is a function of the basic design of the reload. I believe that this is where 90% of the experience and work resides. Establishing raw accuracy(precision), and ES, while the logical starting point, only represents a portion of the requirements of a LRH rifle.

I have found that the only way to truly test and optimize for these factors is to subject the rifle to range of actual conditions, test, and optimize the load if required.

My 300 WM and a few other LR rides have also undergone this type of evolution in load optimization. - - [/QUOTE]
