Looks like your getting your reloads sorted JC,,, only a suggestion when I'm working up a load...
I stick to 1 brand of bullet that I plan on using...
1 type of brass,,, 1 powder,,, CCI bench rest primers,,, and 1 bullet,,, Ha,,, I'm Fuzzy that way...
I do alot of prep on my brass,,, pay close attention to seating the primers,,, and watch my powder charges like a hawk...
0.3gr spread until I see signs of pressure,,, it seems that I find some pretty tight groups in the hotter loads,,, then I reduce the loads from my tightest group till I find the next tightest group at the lower node...
Now I have 2 awesome loads I can run with,,, 1 for hunting,,, the other for the 8 months of the off season,,, a win win...
I like the 1,1,1,1... It produces some of the tightest groups I've ever shot...
6 years running as I strive to improve my reloads everyday,,, the endless learning curve that many of us practic...
Keep up the good work JC,,, feel free to pm me if your interested in the simple man's ladder test,,, my old school shooting friend shared it with me since its easy to do and saves alot of time...
