Without getting sloppy or losing your mind… How much ammo can you stand to crank out in a session.
I did about 900 rounds of .223 Sunday. The first 500 were no sweat, but I was getting insane and distracted in the last 400. I load from primed brass so there’s no breaks for primer tube refills… It’s just foot on the gas.
We talking single stage or progressive?
Well I was talking progressive, but I do use a single too. I can work on reloading stuff for many hours. But straight blasting away on the progressive?? 500 at a crack is all my mind can take.
I’ve never really counted exact numbers, but I’ve loaded 300+ (from case cleaning to loaded) on a single stage before, and could have kept on going but my back was hurting from sitting so dang long. Other times, if I’m being distracted by a, we’ll say a pending (and very vocal) honey do list, it’s not nearly as much :D.
I don’t load as much on the progressive, but I consider this thread a challenge though. So we’ll see…
Usually I load 30 at a time with Pmags. 
Single stage is all I have and I load the same way (from primed brass).
After about 600-700 I’m ready to scratch my eyes out. I have loaded 1200 9mm in a sitting before, but it burnt me out so much I didn’t touch the press again for a month.
I usually will reload for around an hour with my Dillon 550. After that it just starts to feel like work.
No doubt. I’ve been at that point where I don’t want to even THINK about loading. 
That’s it right there. 500 rounds is about an hour. After that I’m done.
I usually due about 1000 round at a time on a single stage press with individually measured powder charges no problem. Takes me all day but that is the fun of it. I usually split the case prep and power and bullet seating on different days though.
Assuming prepped brass (sized/deprimed/trimmed), I load 1 round every 10-15 seconds. I average around 150-200 loaded precision rifle rounds, via a Prometheus Gen 2 and a Co-ax, per hour. I generally only do 50 at a time before I get too bored.
I have done 1500 9mm in one session the most 223 i have done is around 7-800 and those were both brutal. I pretty much do 400 at a time now.
I’ll do a couple hundred a night usually. If it’s crappy out or have nothing to do I can load a few thousand. Wife keeps the primer tubes and casefeeder full.
I stick to a 50-round reloading tray per session on my T-7, but that’s a turret, and I haven’t got my 3BR set up yet, so apples to oranges.
How the hell do you guys load 500 rds in an hour? I can see that with pre-primed brass…maybe…but I’m nowhere near that with all the weighing, filling, counting, filling, and more filling lol. 
Talking .223 here right? I can probably get closer to 500/hr with 9mm…
All I’m doing is cycling and indexing the machine. All I have to do is grab brass and bullets. I just watch each round to make sure the Powder Charge looks ok, and keep rolling.
How fast do you crank the handle? I tend to go very slow and controlled…
I do get some pretty damn accurate ammo though 
Not abnormally fast. My goal is NEVER volume per hour.
Gotcha…so I guess this question is really “how long can you sit at your press and crank out rounds before you go crazy?”
I’m probably good for 2-3 hours, but at that point it’s more of a physical thing than mental since I use a simple wooden stool with no padding lol
I can get into a pretty good rythem most of the time. Radio on, just checking powder charge by eye as markm said. I prep the .223 beforehand, already sized, deprimed and swagged before loading.
I try to not load more than 600 in a day on my Dillon 550.
