Kind of hijacking my own thread here, but have a follow up. I have most of my setup, been slowly working through the process. How many rounds does it take to effectively understand a load? That is to ask if I have 200 rounds, should I try 4 sets of 50 rounds, each set having a mildly different amount of powder, all within the acceptable range provided? For example, if it says 4.5-5.4grains, should I do 50 at 4.5, 4.8, 5.0 and 5.2 or some other arbitrary setup? I'm using Unique powder with 124 grain Rainier bullets and Winchester primers. Also suggestions on more "match grade" stuff would be greatly appreciated, I figured this was just to get me started.
