For shotgun shells, having used the Mec's for 30 years, including the 9000H very automatic version of the 9000G, Mec's are fords compared to the Porsche of the Spolar Gold Premier hydraulic.
You better have LOTS of components and shoot a LOT of shells, because this will churn out huge quantities in very, very little time. Even the much more difficult to reload 410's.
