You're welcome, Sean. The work you do is well worth it.
I mostly use my 550 for 45 these days. I think loading 9 efficiently requires sorting brass and I'm too old for that stuff. Back when I shot a G19 a lot I ran it with a broached barrel and resized my own 125 grain lswcs from .358 to .356. Pretty holes in the paper and the GLOCK gobbled them like pez.
