Just curious, what hulls are you going to us for the 10ga reloads?
I have not reloaded for the 10, but the SP-10 can be picky as to the hulls used. Especially for certain size shot, large steel shot for sure.
Winchester hulls, and shells, were always the best. No problem at all feeding, ejecting or brass splitting.
Federal not so good, from split brass, to out of round factory ammo refusing to feed.
I have no clue if there are generic hulls, high quality hulls, or you purchase certain factory hulls. Like I wrote I never reloaded for the 10.
