What is important to me:
1. No signs of over pressure (sticky bolt, sticky extraction, punctured primers, blowed up

2. Accuracy. If you are shooting sub .5 moa at 100 yards, step it out to 300-400 yards are really define your load. When you have excellent accuracy there, move back in to 100 and out to 500 and see what you are getting. 300 yards is a good range for OCW testing. (Optimal Charge Weight)
3. Good time at the range. This is MOST important, right next to coming home with the same number of appendages and holes in my body that I left home with.
I build my own DOPE for each load. Try to factor in temp, humidity, and wind (even direction of sun).
Just my .02. YMMV
