I started reloading last year with a Lee loader set. The one you use a hammer for to drive the empties into a die for sizing.Amen!
Back in my 550 days, I had a light over the bullet station. I'd look in right before I seated a bullet. Then I upgraded to a 650 and flicked my eyes to the powdercheck to ensure it was moving the proper amount up. Lights and sirens can fail. I'll visually inspect.
Clean your seating die every 1,000 rounds as well. Lube gets in there and will let a bullet stick. There was some guy in a cowboy mag that was either double-charging or double-seating (I think it was double-seating) bullets b/c he hadn't cleaned his seating die in 10's of 1000's of rounds. One bullet stuck in the seater, he loaded the next and double-bulleted the round. Yikes! I think in the magazine article he blew up 3 different 45Colt cowboy guns.
I stopped reloading because it was too many things to watch at once. It was exhausting.
Has to be done one step at a time and I run batches of 50
1. Deprime (hammer and punch)
2. Clean pockets and add lube
3. Resize and prime (hammer to drive the shells into resizing due then add a primer to the base and hammer to seat the primer)
4. Charge seat bullet and crimp (insert shell into funnel shaped seating die.....use a dipper to measure powder for each......drop the bullet in.....set the seating tool on top and give it 2 to 3 taps with the hammer......remove seating tool and shell flip over insert carteridge then a couple taps with the hammer to crimp.....
I can do 50 rounds in 45 minutes now that I'm well practiced. Its slow......but the chances of screwing something up are nill
The set cost $30
All in with scale to check the dippers for charge weight, calipers to measure length, plastic hammer, and a few odds and ends was about $100 all in.
I've made a ton of 38 and 357 with this set.
