Which group is best?

Its why I dont pay alot of attention to Chrono numbers more of what the target tells me. That being said I do use a chrono but not to make a judgment on what group is best.
 
What landed you on this powder charge? What did that group look like? Seating depth for it?

OR are you testing for seating first?

I tried that once...only once.
 
I have the same type of question. Why not mess with the powder charge and see if it helps. Accuracy wins in a comptition not speed. you may even have to try a different powder or primer.
 
Do you have another bullet to try I see I suggest you use a different type of bullet in the same weight class class and see if you get better results the results
 
Well, you guys have talked me into another round of shooting! I'm going to try the other good Sd charge at 66.4 gr as well as comparing seating depths of +/-0.005" to the 0.040" at 66.8 gr…..we'll see.
