    DPMS LR308 - Initial Sight In & Break In ?

    I bought a new DPMS LR308 and I'm going to the range this weekend. I have a large quantity of 7.62 surplus ammo (Port, Hirtenberger and Radway Green) and am wondering if it would be ok to use it for the initial sight in and for barrel break in. Any recomendations would be appreciated.
