[QUOTE="aushunter1, post: 1724710, member: 57533"] For the last 15 years of my reloading experience I have always done it this way without to much failure- I start all my LD at 10 thou off the lands. I go through the recommended range for the specific powder at either .3gr or .5 gr increments depending on that range, if its a 3.5 gr range then I do .3, if it 4 to 5 gr then I do .5gr. This is shooting 5 rounds per group. Once I find a result worth exploring which is usually already at around MOA or under I then start to adjust my seating depth which I then go to 5 thou, 15 thou & 20 thou, again shooting 5 per change to seating depth. Then once I have found the best result from that depending on how it works out I will then try to tweak it by doing .1gr & .2gr powder charge increment changes either side of the best charge amount @ that CBTO depth both on the upper side & the lower side. Don't forget that this all comes out of proper case preparation! *Flash hole deburring *Primer pocket uniforming *Case annealing for good neck tension if not using new cases or multiple fires cases *All the other usual stuff like debur & chamfer, trim to length etc *Using good quality die & press If I have failed by this stage & I really want to use this projectile then I will change powder & go through the same procedure. Everything has to be consistent in what we do otherwise the results are flawed! [/QUOTE]
