I have a Hornady LNL progressive. I reload 9mm, .45ACP, .38special, and .308 Winchester on it. For the handgun rounds, I run the press as a progressive. For my .308 rifle loads, I run just one at a time and have my powder measure set to drop about .5gr less than desired, and then trickle in the last little bit on the scale. By running the rifle rounds one at a time, the seating depth is a little more consistent.
