Here is my Mosin sporter in caliber 6,3x52R (.25-35) made by arms workshop Aarre Viitanen.
.25-35 was quite common caliber in small game rifles (Mauser 96, Mosins, Tikka H-45 and Valmet combination guns) after war years in Finland.
I can't wait for the black grouse season...

Bolt is modified for smaller rim
