Minimum shots/groups to test loads

If shots are within reason (not flying all over the place) how many three or five shot groups would you guys say would be needed to make a decision on a load?
Would two five shot groups be too few?
 
2 groups would be enough for me if the ED and SD were in the single digits.

When I first got into Highpower I got a Bushmaster DCM in .223. I loaded from minimum load to maximum load at .1 tenth grain increase. Aiming at the exact center of the target for EVERY shot starting from minimum to maximum they shot about 3 inches low and went higher until I had 4 shots in a row that
were touching in a nice circle then they started to climb higher until all 16 shots were fired.

A "CLASIC" ladder step to find the right load. :):):)

I never had another one work that well with a bolt action. :(

"Aim small miss small", :D
