In Europe, such questions trigger endless discussions. As always, there are hardly any ideal cartridges for any type of game, including roe deer. You have to know in advance how and where the roe deer will be hunted. There are differences as to whether this hunt takes place in the forest or in a wide open area and which other wild species can also occur and may be shot.The biggest species of game will determine the choice of caliber, in our case above all the wild boar, and therefore the roe deers are often shot with very different cartridges between caliber 5,6mm and even 9,3mm. Cartridges with a smaller caliber of around 6mm are ideal, but you also have to take the bullet used in account. As far I am concerned, I am not an exclusive roe deer hunter and have therefore shot this game with very different cartridges such as 6,5x65R, 7x64, 300 Win Mag, 300 H&H Magnum, 300 RUM, 8x57IS, 9,3x64.
