Unfortunatly, I cannot tell you anything about the ballistics, but one of my good friends shoots a .25-06 and he loves it. He also uses it for deer and varmits. His only regret is that he wants to chase something bigger and the gun doesn't have the versatility of some of the other calibers.
Hey Mike , my friend is a trapper for the Fed Ag. dept. He uses a Ruger 25-06 for all his varmit stuff . It is also his choice for deer . He used it on an antelope hunt we did a few years back. What a low recoil , flat , sweet shootin rifle.
