I have one.
I like it ok and it was a real improvement over the RCBS Jr I had before - mainly for the compound leverage.
I use my Lyman as a semi progressive for pistol calibers with a Lee Autodisk powder measure in Lee powder-through-expander dies. It works pretty good - faster than a single stage much cheaper than a full progressive. Bu t the auto primer dispenser didn't work for me since I am constantly turning the turret when loading pistol carts. I preprocess the cases by cleaning, deprime and size then prime with a Lee autoprime.
I can run of 100 to 300- 400 rounds of prepped cases of one caliber in a relatively short time - haven't timed it but its quicker than my old single stage.
For doing frequent batches I like the set up.
It hasn't been as convenient to switch among turrets as I expected - especially if I'm doing small batches of various calibers of ammo.
don't have the bump problem other complain of.
I haven't noticed any decline in accurcy of my ammo compared to the prior single stage press - alignment seems good.
Drawbacks;
Ram close to center post might be too close for some with big fingers.
rear turret support is a tiny steel rod. Wish it was much heavier and had a roller bearing or something.
primer catcher is smallish and doesn't always stay in plaase. Primers sometimes bounce out - wish they had drilled the ram an put a catcher at the bottom. Primer cather can fill up if I'm processing a lot of cases that use large primers - and I've spilled them from bumping the catcher (light plastic) or they overflow the inner rim that is pretty shallow.
When I got mine Dillion had barely come out with their turret, RCBS came much later, and the current Redding wasn't out yet.
But I'm happy enough with it and will probably keep it.
