I am curious to see Chad's post on here.
LOL! Which caliber are we talking about!!! When I get the Dillon 1050's tuned up just right and running like a good sewing machine, they crank out 500-700 rounds an hour (depending on caliber, generally 308 Win and 300 blk out). Run that for 6 hours press time (about a full 8 hr day's work), and you have 3000-4000 rounds loaded in 1 day. You can do the math on the rest. But I don't run these full time, every day. I'll make a large run to keep inventory up, then switch over to another caliber or press when needed. What kills your time, or labor, is making a caliber change. It takes me about 1-2 hours to make a conversion on a press. This is why I have 3 Dillon 1050's, to reduce the conversion time. One is dedicated 308 Win, one is dedicated 300 blk out and 223 (same shell plate and priming, just change the dies out), and the 3rd press is set up for 10mm and 40 cal with some 223 or 300 blk out work when needed.
I do A LOT of precision ammo loaded single stage as my main ammo. You can see on my new video how I load my single stage ammo. I'll be doing a progressive press video very soon showing the Dillon 1050 presses loading ammo. Single stage ammo takes the most time and is a lot of what I load.
If it's a caliber I load on a progressive press, like 223, 40 cal, 10mm, 300 blk out, or bulk 308 Win, I won't load it unless I'm doing at least 1000+ rounds at a time. If the press is already set up, I'll crank out a few hundred rounds, if needed, for something if I'm out of stock or need something specific. But if it's something out of the normal ammo, it has to be 1000+ rounds to even out the cost to be priced right.
