Without trying to start the heavy/slow v. light/fast debate, I can say that it is pretty easy to get a 250 grain class bullet working in the super (or my Rowland). So no, it is not the correct platform for 300 grain class and up type bullets, but as Reflex pointed out those are not needed in every situation.

As far as I am concerned, these conversions shine less when compared to a dedicated hunting revolver/singleshot/etc, but for the hunter who perhaps carries a Glock (1911) most of the rest of the time, there is something very "shiney" about a similar platform handling more chores. Or in my case, when I am at the ranch, I could be hunting, or I could be warding off large critters or two legged types, or running a chainsaw, or clearing roads or plinking or.....

It's not about having a single perfect gun for hunting, as it is about having a perfect gun that will do more things.
