d-h18 if that is a true 40 yards(measured) that is a pretty darn good pattern you have there!!!!

How many shots did you fire at 40??? I like to fire at least 4 or 5 to get a good idea... I've patterned loads before were I shot one and got like 15 hits in the vitals at 40 and fired the next shot and only got like 6 then the next was like 8 then the next one was like 6... So the first load was a fluke
