After looking a little more into it I am not completely happy with the 9.3X74R as a cartridge, it isn’t nearly as versatile a round as my current 375H&H is and I don’t want to handicap myself by trying to cover too much with the one gun.

I was originally after a new shotgun for hunting Pigs and other medium game with Buckshot and solid ball rounds, much like those used to hunt Boars in Italy.
With that in mind I have started looking at either a Beretta silver pigeon slug gun or a Sabatti SABA slug gun as they are more made to order for my purposes.

The other option that I would look at is a more modular system that would enable me to use it as a matched pair switch barrel Shotgun and double Rifle.
