Thread: Getting ES down with 223

Greetings Pommy,
You seem to have tried almost everything to get the ES down so perhaps there are two questions. First what was different between the high ES loads and the low ones, and yes it was the cases. The second question was does it matter? You and Micky obviously differ on this question so we are back to the cases. You have ruled out most of the obvious problems but have not mentioned flash holes. I believe Lapua cases have their flash holes drilled but most others are punched leaving a rough edge inside the case. Might be worth uniforming the flash holes using the flashy tool designed for this. Primer pockets as well? Otherwise its back to micky's solution.
Regards Grandpamac.
