Look at the case feeder manual....( there is a tab at the top of the case feeder that you can bend a little...that causes a case to tip out of the case feeder plate unless its in the right side up ). You need to adjust it a little to get it to work just right...so the upside down case tips out instead of dropping into tube - because the cases are bottom heavy..
But yes, you will get one upside down in the tube once in a while...
As you operate the press...look at the next case to drop into place for station one, you can see if its upside down easily ( just remove it - and toss it up into case feeder ).
A .22 case inside a 9mm case..means you are not inspecting your cases before you drop them in the case feeder...that's your error, not the press. I keep an 8 gallon tube of ( cleaned, inspected and sorted cases by caliber - there is a lot of junk cases out there that you might sweep up --- and you need to sort them out )....and one 8 gallon tub of dirty brass in that same caliber. Don't be in a hurry - inspect the cases carefully before you drop them into the case feeder...
With experience, you can feel when the primer is seated properly...if it doesn't feel right ( pull the case out of station 2 and check it ) -- if its ok, put it back.
