Pretty much depends on what I am doing. I can not be restricted to one gun due to being involved in more than one shooting sport.
Let's see how many "firearms" a sportsman needs to have in possession.

Air Rifle target = indoor and field target - minimum 2 + spares and varmint shooting = several.

Varmint powder burners, CF and RF - several of each calibre .17's and .22's both CF and RF.

Big Game CF, from coyote/wolf to elk and moose = at least 3 rifles

Upland Birds, turkey, migratory game birds = several shotguns

Black Powder = CF Rifle Ctg.- at least 2, Percussion and Flintlock rifles and shotguns, Flintlock handguns and Percussion handguns, as well CF handguns.= many guns

Handgun target shooting, ISU, Cowboy Action, IPSC. 2 for ISU, Minimum of 4 for CB Action and at least 2 for IPSC - revolver and auto.

Can't or couldn't choose one - I need them all.

BUT - The rifle that makes me smile the most when I'm shooting it, is this one:
