As an update to my "speeding up the process" dilemma:
1) As mentioned already, I have gone full bore to priming on the XL650. Big increase in throughput, and I am never going back to hand priming for pistol rounds.
2) Minimal brass sorting: I am still going through my cleaned range brass and culling out the bad cases (very few), and a few brands that seem substandard (Tulammo, FM, etc.). I also separate out the crimped NATO primers (I seem to get a fair amount of those, maybe 10-15 out of 500?), but for the most part, it is pretty quick and has saved a ton of time.
3) I am now wet tumbling without decapping, and I now decap as part of the loading process. HUGE time savings!!! Who cares about nice clean primer pockets again???
All in all, I am actually in an ammo surplus mode for the first time all year! I have about 1,200 rounds of 9mm stocked, and as soon as my new bullet order arrives on Tuesday, I want to get a couple of thousand more loaded up this week. That won't last very long (I am at about 11,000 rounds fired for the year), but it is better than being "Old Mother Hubbard who went to the cupboard to get her poor SIG some ammo"! At least I am making progress...
Now to get moving on the .45 stockpile. I am literally down to about 50 rounds.
You're shooting 10k+ and still looking at headstamps and primers? My brass gets sorted with the shell sorter bowls, dumped into the tumbler, then a quick shot of oneshot and thrown into the case feeder. Practice ammo goes straight into a ammo can. Match ammo "typically" gets checked with a hundo gauge. Anything that fails gets thrown in the practice can unless there is an obvious crack or something.
Are you wet tumbling with pins? A lot of shooters don't bother with the pins, you just need the outside of the case clean. That would save time as well.
For 45 on the 650, I go ahead and size/deprime ~50 extra cases to have in a bin. That way when you run into a small pistol primer, just pull that case out, pop the previously sized/deprimed case in, and keep going. Throw the small primer case in a tub to save for a rainy day when you don't have large primers. (That's assuming you don't sort before hand. I would much rather handle 5 or 10% of cases that way instead of handling 100% of the cases sorting by hand.)
