1.3" isn't all that bad. If you wanted supreme accurcy then you should have bough a varmit/bench gun. Buying a hunting rifle and then asking it to shoot a 1/2" group at the range seems to be asking a bit much. I am surprised it didn't shoot under one inch though. I don't think there is a company out there that has produced products and had lemons in the bunch. Some guns just flat are not going to shoot.
