How many times do you have to use 9mm brass before you have to trim? I plan on using minimum loads at the beginning. Just wondering if a case length guage is in order also.
I just started reloading, and I have the Lee 50th Anniversary kit. It's single stage, and is super-simple to use, quick to change out the dies, and easy to set up. I've never used a turret press, but for my $.02, go with the basics at first.
As for case length, I just picked up $30 digital calipers from Home Depot, and those work just fine for me. Case length, diameter, thickness, whatever. They're not SUPER accurate (+- .02 mm, give or take), but they work well enough for me. I reload .223, and I've done about 3 reloads off the brass I have, and it's still spec length.
Also, any experts here have an opinion on small-base dies as opposed to regular for automatics?
