Choosing from my current collection and assuming I could always get components for my choices.

Dakota 76-.338WM-Micky Hill Country stock-custom irons and mounts by BC's only gunmaker, Martini's and two scopes in Talley QDs.

OR-Brno ZG-47 Original 9.3x62, Micky MKX stock and Recknagel peep-front blade-Talleys-two scopes.

The scopes would be either Zeiss Conquest 4xs or Leupy VX3-1.75x6MHDs.

Browning-Miroku Mod 7500 combo. O/U gun, .308Win-12 Ga. scoped and irons on it.

Ruger GP-100 sts-4" .357 Mag.

So, one serious big game hunting and Grizzly defence rifle, one general purpose "meat gun" and one self defence tool, all of which can be handloaded and are legal for all BC game.
