I have not tried Cheddite hulls in 10ga. What I do know is Federal is all brass, Remington and Winchester have steel in them. The steel hulls are tough on the resizing rings. I recently changed the resizer ring on my Versamec and I see a big difference. Shells that would not allow me to close guns with tighter chambers than my Parker will now close without problem.
How old/how much use has your 10ga resizing ring seen? If it's a lot or I don't know I would get a new one.
The stand alone Super Sizer works well too, but with the new resizing ring I won't be needing it as much.

PS. I have not seen Federal 10ga hulls available anywhere lately. Remington would be my next choice.
