Howdy:
I have just loaded up 50 rounds to determine what charge weight works best with my S&W686 & components.
I loaded 10 rounds for each weight of powder, starting at 10% below max and going up to max (5 different charge weights).
I was wondering what most of y'all did as to groups:
1 fouling shot, 3 groups of 3
2 groups of 5
1 group of ten
Something else?
I intend to find the powder charge(s) with the tightest grouping and then iterate again, dividing the range up into 5 charge weights. I hope I'll have a good load tuned to my S&W at that point.
Last: do y'all clean the bore between groups? I will start with a really clean, copper-free bore.
Thanks for your input.
