Hey adweisbe,
Don't worry, you are doing the right thing - for you. From your very first post to your last, it is obvious you will never be satisfied with the Hornady machine, no matter what they do to make you happy. I wonder, however, what you will do when you order a Dillon or some other machine, find a problem with it, and then go through the same thing with that manufacturer? Dillon and Hornady produce really good machines, and they usually do a pretty good job of fixing things for the customer. Some customers, however, just refuse to be satisfied.
I have had a Hornady L&L since they first came out about 15 years ago, and I have not had any personal experience with Hornady's warranty service. That is because I have never had any part break on my machine - none. And, no, I have never had any problem with any of the 30+ bushings I own - they all lock in place and stay there until I take them out.
I loaded shells for three decades on single stage presses. When I first bought my L&L, I had a pretty good understanding of reloading and how reloading machines worked. After unpacking the L&L, I read the manual quite a few times before I ever attached it to my bench. Once attached to my bench, I spent a lot of time reading the manual and observing how each process worked as the handle was moved down and up. When I first started to reload some cases, things went pretty smoothly right from the start. I learned about the primer feeder sticking and the problem with getting the last one or two primers to feed. Both problems were obvious, and I was able to smooth out the primer feed process, and I came up with a solution to the last few primers in the tube. The machine is a good machine, but it will not satisfy those who refuse to listen and learn.
There are many folks here who are very happy with their Hornady and their Dillon machines. If one listens to them, they can help one with a new machine.
Best wishes,
Dave Wile
