Hi Antsman, had the same problem with my Howa 308 and Hornady SST ammo. They were slightly tight new when first fired in my Howa.
Then when I resized them to reload with my LEE die, they were still tight to chamber.
I then tried my RCBS small base X die I use for my BAR 308. All sorted! Cases now resized for both BAR & Howa.....
I suspect my Howa has a very tight chamber that requires that little bit more squeeze on the brass to reload?
