Having my VangComp 870 delivered on Tuesday and am wanting to print several different loads to see which does best.

When testing different loads, do you test at specific ranges or max range that I would find in my house?

Any loads that you guys may have used and found to print very well?

I've been collecting #4 buck (and some 00 buck) for awhile and been gathering different loads to print. After seeing each print, I'll decide which I like and start buying excess of that certain load.
