Chronograph numbers and accuracy don't always go hand in hand. I have witnessed several loads with 60 fps swings that grouped really well. And some like the loads shown here that didn't group well. but.....aint there always a but...if I get a load with a really low deviation, I have always been able to play with seating depth to make it shoot well. A few times, just for testing, I have lengthened the throat and it worked. Put no faith that a low SD means absolute accuracy, and put no faith that it wont.
