Dynoman: Yes, it is a progressive loader, and it works exceptionally well as one. I noticed one day that it put much less force on the press when I placed a single brass in it and completely ran that 1 piece of brass completely through all 4 stages of the press. I check the powder charge weight every 5th round and loading it as I described allows me to do that. I'm an old man, I'm retired, I'm not in a hurry, and I have come to enjoy reloading as much as do shooting. I developed heart issues and started having anxiety attacks a while back, so the most important thing to me is to de-stress myself and take things in a slow manner. The last thing I want to do is have a squib load which generally results in a bulged barrel in in any of my .45 autos. I bought 2 new .45 autos this last year, a Wilson Combat Classic SG and a Ed Brown ET, and I am not interested in squibbing either of those guns. Well, nor my Hoag long-slide, Les Baer PII, or my Springfiled Armory trophy Match.
