So what are the problems?
I sold a 550 to get the LnL with a casefeeder. I had some issues but tey are resolved pretty easily. The one area that the LnL beats the 650 is with the case slider setup. It captures the base of the case so it can't tip, it also is easier to adjust. BUT, once you get the LnL adjusted you actually never adjust it again. I also like how the LnL has the casefeeder slider on the left not the right so if you do have a issue it is super easy to fix. To me that is the only place the LnL needs a little extra TLC then the Dillon.
Well it almost always primers or that whole Assembly. Now you have to understand the lnl is not new to me as I am closing in on 100,000 rounds. Its just when i switch calibers or from large to small primers, I can't just switch and load its adjustment after adjustment get rolling bang lock up take apart again clean then back to reloading bang stop again. I loaded 1000 yesterday had 5 stoppages about 1/2 hour total time. These were all my 9mm load I have become a expert on the feel of the press but load quite a bit on it and just want to sit down crank them out clean up be done. Maybe I am asking to much maybe the Dillon owners have the same problems I don't know thats why I am here I guess.
I have a pic of my bench and setup in the non dillion section now. I don't know how to cut and paste the link. Sorry
Let me take a second to thank all the above posters it means a lot to me with your suggestions!
