true... if going beyond 100m i'd say 30-30, but under the .44mag is a fine choice, for ammo selection, mag caapacity, and overall cool factor.
Mind you, you can find 30-30 ammo almost anywhere that sells ammo. If you handload i'd say .44 mag because you can load it much hotter than factory and the available bullet selection for .44 is much better than for a 30-30.
If you dont handload, i'd say 30-30 because factory ammo for it is pretty devestating these days. the leverevoloution ammo is pretty potent stuff. and all other things being pretty similar it will also give you the extra range on the off chance you should need it, making the gun more versatile overall.
