Sombody mentioned 25-06 (metric 6,5x63), 6,5 Mannlicher (original 6,5x54 Mannlicher schönauer) and 6,5x55 Swedisch Mauser as good alllround cartidges. I never used 25-06 but I own M 1903 Mannlicher Scönauer full stock carabine in 6,5x54 and I used it manny times (today only ocasionly). With RWS and Hirtenberger ammunition with 10,3 gr. bullets it is a nice handy high quality rifle wery acurate capable to take any game depending how good the schoter is but with certenly limitation of range and power in my exprience 150-170 m and 100-120 kg game weight. I hunted too befor for several years wit
