why not, I'll play.
Tikka Varmint .223 - I have one that is predominantly used for target shooting. So accurate as a factory rifle. If I ever get a chance to chase dogs, roos etc it will do that incredibly well also.
Tikka Varmint 6.5x55 OR original Swede mauser - Time tested caliber in a modern action will do amazing things for longer range paper punching and going after the bigger game (if I ever get into that). The Old Milsurp is Mauser in this caliber are simply excellent rifles for all applications.
Lever action .357 - tremendously fun gun to shoot, plink with. Carbine comps with this at my local range are fun too. (this assumes pistol caliber powders and items are available for reloading). I recently owned on (Marlin 1892 CS) and sold it. I want another one
Bolt action .280Ack Imp - for reaching out long. A really nicely balanced 7mm that can achieve great performance without going into magnum dimensions and issues.
BA 22LR. Cheap, reliable, proven and a great plinker and bunny buster that you can shoot all day without draining your bank account.
that would be my 5
