Ammo is indeed a different ballgame, but I do want to make one point known:

Weatherby rifles (for the most part!) are chambered in Weatherby calibers. That's ammo that hard to find and horribly expensive. No other guns (outside of customs) use them. So if there is Weatherby ammo in with all the ammo, you should at least separate that out and give the buyer of the rifle the option of buying that ammo.

Any guy with half a working head on his shoulders will want that particular Weatherby ammo, and very much so.

Now... was your Dad a reloader? If so, he's got a heap of tools and brass and components, all of which is also sought after. With that stuff, I could likely help quite a bit in pricing it and selling it would be no more difficult than an Ebay or Ebay-type auction. The powder and primers can't easily be shipped to buyers, but all the other goodies can be.
