I just started using the super 1050 for my 9mm major ammo. I had trouble the first time using it with primer feed problems but found out later it was a very minor problem which was cause by powder spill. As a new 1050 user, it took me a while to figure out how this machine works. After so many weeks understanding how this machine works and tweaking this machine, it sure is the best out there. The only thing I did was to make sure it is clean from spilled powder. Using one shot case lube made a big difference and is a believer of the product. Thanks to all who suggested this product.
My next problem was having a ring at the bottom of the case using a 38 super undersize decapping and sizer die from EGW. It got to a point that it shave's a good amount of brass at the bottom of the case causing a ring which is also rough resulting to poor magazine feed. For days, I was using a single stage press using a Dillon 9mm sizer die running each case before putting them in the casefeeder and it solve the problem but not the effort and time. Finally got tired of doing it and found a remedy for the problem.
*** TIP *** I ended having to install the Dillon 9mm sizer/decapping die on my 1050's 1st stage and remove the expander die on the 2nd stage and replaced it with the EGW 38 super undersize sizer die - can use a 9mm undersize die too instead of the 38 super **** make sure you take out the decapping pin before installing your undersize die in the 2nd stage ***. To make sure all my loads are useable, I installed a LEE factory crimp die on my last stage. I was very pleased with the results of my loads which where very consistent when is comes to gauging my ammos. Now, I got no ring problems at the bottom of the case and have more time doing other chores instead of spending time in my single press running each case through a sizer/decapping die. This setup may be too extreme to others but in the end, it will save me money not throwing away loaded ammo that does not fit the gauge or spending time using a bullet puller separating the bullet, powder and brass.
