I just spent two months reading and researching progressive presses because I am getting into more handgun shoots and I could shoot in one evening what it took three evenings to reload on a single stage.
After looking at all the angles, I bought a Hornady LNL. I was completely sold on the Dillon XL650 because of it being a machine that didn't require "tinkering"... And then I tale to several Dillon owners in my club who started telling me about all the "tinkering " they had to do on their 650s.
When I compared the $ investment and the fact that it would be very costly to load several different calibers on the Dillon, I went red.
I was willing to pay the extra bucks for a out of the box and it runs machine, but that's just apparently not true. They ALL require dinking around, but as someone mentioned above, watch 76Highboy videos on the Hornady LNL and follow his suggestions and everything just runs. I have cranked out over 1000 rounds of the LNL without issue . .. well, there was one issue.... the nut behind the handle wasn't watching his primers and let them run out so he had two cases without primers in them on one batch... but that was hardly the machines fault.
In addition, Cabela's has them on sale right now for $60 off regular price plus you get 500 free bullets (you pay $14 for shipping) from Hornady. It's an awesome press IMHO. Dillon is great too, but with the sale price, using my Cabela's bucks, I was out the door for under $200 with all of what I needed for all 3 calibers not including the free bullets.
Also, I didn't buy the case feeder for the LNL as its easy to run without it, but the Dillon really is set up for running a case feeder. One reviewer made the comment accurately the to run the xl650 without the case feeder is "just plain silly". For me it was $200 for the whole enchalada or a little over a grand to go blue....
