[QUOTE="Capt. D, post: 2785417, member: 10225"] I'm in the 1/10 grain camp. I've seen a tenth make a difference but not less than that in my experience with the equipment I have. There are other things that make a difference from form to seating depth and everything in between, but powder charge is where I'll make my 1st adjustment. I think that I have my brass prep where it needs to be as consistent as I can. Bottom line is; if you think it might help, test it. Then if you think it does help, do it. I'm sure I probably do things that others don't and I am sure I don't do things that others do. I'm always trying to learn and will often times try something that I've heard or read to make things better but often times I can't tell the difference but it's an excuse to head to the range. The one thing that has been the most help to me is advice I got from a bench rest shooter friend of mine is reading the groups. Assuming no shooter errors or mechanical problems: Vertical Group, barrel is asking for more powder. Horizontal Group, seating depth issue or needs slight powder increase. Diagonal Group, adjust neck tension. Double Grouping, load is too hot. Reduce powder charge or change primer. Round Group, barrel is happy. [/QUOTE]
