@haisardao,
I will add that ES/SD are not the be all, end all for accurate loads.
My 22-250AI used in short (300mtr) F-class had a load that wasn't good for ES, above 60fps…but at 300 it would put 10 shots with 8 touching and the other 2 touching each other a few mills away from the main group. Also, you can have a load with excellent ES/SD but spray bullets all over the target, this is because barrel oscillation variation with that load may be wide or at the point where the barrel is at the bottom or top of it's whip, it happens.
Cheers.
