Case head expansion is a sign of pressure but does that mean you can still use the case or not. The expansion was .003. Primer pockets were still tight

I've never measured case head expansion. I've used other pressure signs from what I've learned , right or wrong. If brass holds a primer , I shoot it. If after a few firings I get a little leakage around the primer , I scrap that batch. I use a few pieces for test before loading a whole batch . I run my 17-204 pretty hard, have enough brass and bullets to ruin the barrel.
If you are worrying about brass life back off the gas a little.
