40 seconds between shots keeps you going for a while?
Hmm, I'd say it kept things manageable for a short run.
I was only changing powder charges in the initial photos so it was only 24 shots, not exactly a barrel burning quantity of ammo.
If you were shooting more shots per group, shooting a load with a wider range of powder charges, testing different bullets, primers etc. you could be looking at 100 - 150 shots or more.
I'd be leaving it a lot longer for that much shooting.
