I have a "press"ing question

[truckdweld]

So i finally got all setup up with the new lock and load. I tumbled some brass and went to town.

First i sized and de-capped some .223. I lubed the cases up in a ziplock and everything went smooth.

I switched dies and tried to run some .270 win brass. The brass would only go into the sizer 3/4 of the way into the die. As i removed the brass i could tell that the mouth and neck was damaged. This same thing happened with the .308 win brass. I then tried some 300wsm and they work as smoothly as i would expect.

What is causing this issue? I treated everything the same way and adjusted the dies per Hornady's instructions. Here are some pics of the damaged .270 rounds.

What dies are you using?
And what press do you have?

Could you have mixed up some of the dies (made for use on the other brass)?

perhaps you got the sizing buttons mixed? It looks like damage from an oversize button.
