Its a shell built using the Cheddite hull. If your gun or guns had issues extracting them, theyd probably have issues extracting ANY shell built using the Cheddite, including but not limited to RSTs. Seeing how pretty much all Cheddite hulls are built the exact same way.

And why on earth would you use shells that have corroded heads? That in itself would more than likely lead to extraction issues in any gun. Good lord.

On the flip side, my shooting buddy has shot oodles of those Italian Herters loads in 16 gauge, I never witnessed an issue. He gets about 4 to 5 reloads out of the hulls too before theyre trashed. I myself have popped off around a thousand or so of the 12 & 20 gauge loads without a hiccup as well. Even a finicky Franchi 48 chews em up and spits em out. Thats saying something.
