Having a combination gun is a bit like having an Enduro motorcycle-sure, you can ride on the street or in the dirt, but, it is not the best, not even close, for either.
Get a dirt bike, or, get a street bike, or, get both.

Get a rifle, a good, accurate rifle with the optics you need (almost nobody here is using iron sights these days) and get a bird gun, a really good one, and use either for their intended purpose.

A deer poked its head in a cover you were hunting grouse in? Let him go until deer season. None of us is starving.
Best,
Ted
