Machine Gunner
Loaded my first batch of 100 rounds of 9mm. Loaded them in single-stage mode, where I resized/deprimed/primed them all, then ran thru them all thru the expander/charging die, then seated the bullet on all rounds, then crimped all rounds. Before adding the bullets, I was able to inspect all the charged cases side by side to ensure they all looked right.
I'm using the lee auto-disk powder measure with the adjustable charge bar. After adjusting it, its takes a few charges to settle in, then it seems to stay very consistent. For the first 50, I measured the powder charge of each round. For the next 50, I just measured every 5th or so, or if something didn't feel quite right. I was trying for a charge of 6.0gr, and the entire time I never saw a charge under 5.9, or more than 6.2. Most were 6.0/6.1.
I think by the next batch I'll feel comfortable starting to use the auto-indexing mode on the press. I'll probably single-stage the first 10 or so, so that I can weight the charges, then go auto-index after that.
