The ES showed itself at the 300 mark but still not bad. While with tuning I cut the ES down to 30 which is ~60%, my groups didnt shrink 60%. 🤔

Interesting. Thanks. This is neat.

I might be thinking about this wrong but hear me out.

ES of 75 - shoot a .75 MOA group
ES of 10 - shoot a 1 MOA group

Which one would I feel best about reliably repeating those group sizes over a period of time (assuming condition not a factor, 10mph wind or not etc) and assuming nothing else changes like powder lot, primer, seating depth etc.?

Does that variability in the ES75 group's ability to repeat actually matter? That is to say it might shoot a .75 or 1.25 due to ES but that's NBD if 2.0 MOA is good enough.

So the ES10 offers an "advantage" because it's more likely to continually print 1moa but the standard is 2moa - so who cares?

Probably thinking myself into a hole at this point lol.
