Yes, there sure is many ways Calvin , it is sure different from centerfire BR  when it comes to testing ammo . i still use the wind flags i got off you a few years back , they are great . i will try the Hoehn method too . thanks for the info , steve .   

My barrel is a benchmark as well Phil . I have a Harrells tuner Calvin . i have had good results with center x , and did try some Midas  as well, it seemed to be better than center x . i started by fouling  the barrel ,then shot ,5 shot groups at each number 1 -5 on the tuner . i shot 5 shot groups because i shoot center fire BR  , i will have to try the 3 shot method  . Is everyone shooting at 50 yards ? . i did some shooting at 100 yards on a calm day just to see , again 5 shot groups , midas won that one .  Thank you to everyone that replied . there is some excellent info here .  Steve .

I have a question , i have a tuner on my Barrel , should i remove it , and then lot test to see what will work the best ? . Or leave the tuner on and lot test .  i have heard several different ways to lot test . i would like to order several different lots of ammo to test . any help with this would be great . thanks , Steve .
