Good old caliber for heaver game. American version very similar is called .35 Whelen. It's considered less potent only because twist rate in rifles so chambered is suitable for lighter projectiles and heaviest commercial ammo is loaded with 250gr bullets. Frankly in America I would pick .338 WinMag instead. One of the finest chamberings in pre-64 Winchester is .338 Winchester Magnum (right next to .270 Featherweight) , avant grande!. whistle
