Curious to know what you guys do for qc. Here are my steps for rifle:

Case prep
After depriming/neck sizing
* Trim to length (only done after 2-3 firings) +-.001 else mark as failure
**Chamfer mouth inside and out
* Polish cases with fine steel wool
Inspect case
* *Brush inside of neck
* *Clean primer pockets
* *
After 2-3 firings*
* *Check bolt lift on empty cases, if heavy..
* * Measure headspace using rcbs precision mic
* * Push shoulder back*
* * Measure to within +- .001 else mark as failure
* * Trim to length**+-.001 else mark as failure
* *Chamfer mouth inside and out
* *Polish cases with fine steel wool
Inspect case
* *Brush inside of neck
* *Clean primer pockets

Cartridge loading
Prime case:
Feel primer for correct depth no measurement, though I have a go no go gauge*That I do not use

Charge case:
*Weigh each case (after head stamp sorting) and group to nearest 1-1.5gr
*Measure each charge to exact weight and charge

Seat bullet:
Weigh each bullet, group to nearest .1 gr
Seat bullet to .002 of target oval using hornady comparator, mark failure
Check concentricity to .003, mark failure*
Visual inspect cartridge

Anything marked as a failure that cannot be "fixed" (Ie if the shoulder is pushed back to far) is marked in red then fired in normal groups to see effect.

I think that's everything... Curious what you guys do..
