Thread: HOW IMPORTANT IS ES

The Q would be is there a noticable improvement in grouping between the two? if not then ES maybe the better measure, if yes then the SD is surely? Next time I intend to take an old digital camera up and record the shots as they arrive, just have to hope the battery is still OK and no idiot shoots it...and that includes me, LOL the nasty is the shrapnel when others are wacking steel plates.

If I had to choose between those two hyperthetical strings to progress fwd with my load development, keeping in mind that such small samples are statistically suss, I would choose the first one and try to explain why 1 shot was out from the others. Could be many reasons. Groups at that stage could be less than perfect despite low ES and favourable SD. Time to frig with seating depth. Yeh, seeing your shot fall at say 500yds (must move out to at least that range once happyish at 100yds, but probably 250 for hunting type conditions) needs to be recorded in order against your brass fired. Also keeping your brass once fired in your box in order. Have seen guys trying to do serious long range load development arrive on the mound and tip a whole lot of loaded ammo out of a plastic bag on to the grass! And once fired they are all returned to the bag, assuming none got lost. Seems they are a few of use building camera systems right now similar to 7mmsaum's.
