I was working up some loads the other day, going from book min-max in 1 grain increases and everything looked fine pressure wise, no flattened primers, heavy bolt lift ect.. I found 3 powder charges in the middle that shot/grouped very well at 200 yards. My second to last charge opened up and my very last, book max, shot a horizontal string.
I still did not see any over pressure signs at max but what is that horizontal string telling me?
