[QUOTE="Trnelson, post: 649522, member: 42308"] Not to pick the fly poop out of the pepper and bore you with detail I'll shre how I do developement when i change bullets, powder, primer or brass. Usually... When i start a new setup I use new, weight sorted, full length sized brass so that variable is at least "standardized". Next I pick the bullet I'd like to play with, being certain that the tube should be able to stabilize that weight of projectile. The bullet weight guides me to the powder type or types I want to use. I usually start .015" off the rifling, just an arbitrary choice but I haven't had a rifle that shot best at >.015" so IMO its a good place to start. After a simple load ladder work up to ascertain safe working pressures in my rifle I look to build at least three, but preferably five, loads with each powder at 1 - 2 % increases of charge level. Shooting though the chronograph to monitor velocity noting best SD, ES and average speed of each load I also look to what groups the best as well. I play with setting depth last and move forward .005" at a time. One of those will be clearly tighter even at .015" off the rifling. I load three groups of five at each 5,10, & 15 off. If .005 and .010" off shoot reasonably the same I'll try .008" and .006" off the rifling if neither of those will go 1/2 MOA I try .007" and .009" off. You get the idea.
