Hello Pondoro,
it is a very good caliber for boar hunting concerning your northern birch-trees.You can shoot through the trees and the animals will fall.The maximum range for a good shot is around 120 meters.Can you post a photo of your gun in the forum or on my mail adress ?
I use M.Schönauers as my favorit rifles.
kind regards Johann from Austria

P.S.I have also a reloading equipment for the above mentioned caliber.
