I am just getting into 6.5 Grendel reloading and I plan on sticking with 123SST's since I want to have the ability to hunt with it without the hassle of working up a separate hunting load. I have two powders to try - Tac and 8208XBR. I know I won't be happy unless I'm reaching the velocity potential of my barrel (20") so I'll probably start about halfway between min and max and then work up .5gr at a time for each powder to .5gr above max (unless max is a compressed load). I'll load 4 of each weight (5 just seems like too many but three doesn't allow much shooter error). I then proceed to shoot each group, running a bore snake after each four round group and allowing the barrel to cool. I may start with a group of factory ammo for a baseline and to warm/foul the barrel. At the end of the day I hope to be able to see the nodes and then pick the right load for my gun. I then write it down in 10 different places so I don't lose it, take photographic evidence, chrono it, hahaha you get the story.
What's your guys's load development methodology?
