So what I basically have is a very nice collectible contract Mauser that if I want to shoot and get consistent accuracy is to use specialized loads which you guys get to grill me again on the fact that I don't reload thus cannot conjure up a load that will shoot good consistently in it. Other than that if I want good shooting using factory ammo with my 7x57 contract mausers I have to turn to one of my other ones.
This is sort of the same situation it seems with the Carcano where PP ammo diameter bullets are not correct but at least Hornady though expensive makes the correct diamter ammo for the Carcano. In this Mauser , S&B is a crap shoot and Prvi is worse.
What eastbank said about the diameter just makes sense now, it wasn't just the wind or a bad day shooting Sunday why I had disappointing groups.
