isn't this just a few % increase in case capacity over the 32-20?
I never thought I would be 'that guy' when it comes to experimenting with wildcats. But in a singleshot, why not go with a 32-20? Especially if you need to find a reamer and what not for the barrel.
In a levergun however, this would be fun because there are 357 level guns. So I would guess 30 bobcat would feed pretty well in the modern levers. Cant really find many 32-20 modern lever rifles.
