This past winter I had a major meltdown with my Super 1050 I bought in November. Didn't load correct right out of the gate. .223 Remington was a f-ing joke. Spent many hours trying to figure out the problem. Even Dillon reloading jedi masters couldn't fix it. So I had it set up for 9mm since I had a fairly respectable dealer order for some ammo. Was going along pretty good (although the dealer canceled the order leaving me stuck in a bind). Few hiccups with the primer system. Sometimes a primer would get jacked in between the primer slide and the shell plate so I had to take off the system, clear it, then readjust and back in the saddle. I've loaded plenty of 9mm on the press, over 40,000 rounds by the log book. No issues. No swage rod issues, no priming system issues, no indexing issues. So I had a break while waiting for my next batch of 9mm bullets to arrive and I thought I'd give the ol' .223 another try. I saved a small batch of components in order to do some T&E with the press to figure the problem. Ran out a small batch of 500 trouble free rounds. Same components, same lots, same settings, no problems. I think the press just needed some breaking in. Be that as it may, I've still decided it isn't worth the trouble and won't be loading .223. I'm doing only pistol ammo now and only 9mm and .45 for mail order. Got the 1050 set up for 9mm only and it runs well. The 550 is dedicated to the .45 and the other odd stuff for the local dealers. When I get caught up with stuff and can buy a 1050, it will be for the .45 ACP surely. So to others contemplating the purchase of the 1050: Buy from Dillon direct and use their stretch pay program ($500/mo for 3 months, basically) Give it time. Learn how and why it operates. Learn the adjustments and how they affect others. Go smooth. Go slow. The swage rod feature is excellent, but you will have to determine the practicality of the $1,000 cost over the 650. Knowing what I know now, I'd still do it all over again. I'd love to get a bullet feeder for it. My uncle has one and my last visit to try it out netted me 1,700 rounds an hour. I can live with that.
