Ah, but +/- of WHAT spec?
10% +/- is a lot, that is more than the difference in loads from 3031 to 4895.
Powder charge for standard pressure-velocity?
Closed bomb "burn rate?"
"Pressure curve?"
I must have been lucky, both kegs I went through in my F class phase were as close as my chronograph and target could show.
