I have a Lee 1000 Pro and like it. However, with my method of reloading .223/5.56s it just isn't suitable. I trim after sizing and that just isn't in the cards for a progressive. I have sized and trimmed on my single squeeze press, then ran the partially processed brass in for priming, charging and seating. But, I can use a hand primer and powder dumper about as fast.
With that said, I love to feed clean 40S&W and 45ACP brass in and have completed rounds fall out the other end.
Remember, keep it clean and well oiled. The operating handle must make full and complete motion both up and down, that's where the work is done.
I'm thinking seriously about altering the setup to load 300 AAC Blackouts on my 223 bottom plate.
