Mec Help

Hey guys I recently purchased a used 12g Mec 600 Jr. I noticed the support tube would bottom up on the machine before the handle would. This is after raising up the resize ring as high as it would go. Can you measure their support tube so I could compare it to mine? I can't find anywhere online the length it should be. Thanks for your help.

There were two different sizes of support tubes - one for 2.75" shells and one for 3" shells. You also had to raise the column when loading 3" shells. It sounds like you have the support tube for 3" shells and the column is lowered for 2.75" shells.
