It seems you have found a very well priced medium calibre double to get started on.

Try it and if it works it works.

I think such a rifle if it shoots well, regulates with the ammo you use and if it can also be scoped will make a fine medium calibre hunting rifle.

You have the advantages of any double:

* often shorter in overall length, so handier;
* very fast second shot, good for running game or game in close cover;
* the fun of any double rifle.

I too like the aesthetics of a side by side but that wouldn't stop me from buying an under and over in a medium calibre up to 9.3 mm.

I think the speed of reloading the two barrels is over-emphasised in discussing medium calibres. No doubt about it, the time between the second and third shot will be longer for a double than a good bolt action.
