The deadliest ?
Speaking about rifles, it is my old Blaser R93 in .300 Winchester magnum ! The professional camo stock has lost most of its pattern because of my sweat and of an intensive using. It is topped with a Swarovski Z6i 3-18x56 and I changed the factory trigger against a Bix'n Andy trigger. It has shot over 2000 rounds and it is still accurate with my handloaded ammunitions. One of my PH used to name it "my wife" because it was really a deadly gun in my hands.
I'm not able to tell you how many hundreds of games it has killed but I'm sure over 500 now : Wild boars, roe deers, red deers, mouflon, chamois, barbary sheep, foxes, badgers, racoons, nutrias, hares, jackals, guineafowls, porcupines, baboons, klipspringer, steenboks, duikers, springboks, common impalas, black-faced impalas, kudus, elands, blue wildebeests, black-wildebeests, red hartebeests, cheetahs, giraffes, red lechwes, Hartmann zebras, Burchell zebras, blesbok, warthogs, oryx, spotted hyena, waterbucks and maybe others.
And because I used to be a small game hunter at the beginning, my deadliest shotgun is my old Miroku 7000 in 12 GA 2"3/4. My father bought it the year of my birth and I started to use it when I was still very young. Despite all other shotguns I used, no one fitted to me like this incredible Japanse weapon. I shot a lot of pigeons, rabbits, european starlings, thrushes, black birds, woodcocks, ducks, brown hares, foxes.... and also some boars and roe deers.
