TestingSo what is the preferred method to get the lowest possible extreme spreads.
YesWhat affects ES more, powder type, powder weight or primer?
Ive had spreads that were over 100 and was still grouping under sub moa @ 200.
It is practicaly meaningless at that range as you can have one shot 1 7/8ths low and still be sub MOA. Try it at 600 +
