I recently purchased some SIG Match Grade Ammo in .308 from two different sources. One source the boxes are marked SIG Marksman Elite Match Grade while the other source is SIG Elite Performance Match Grade. SIGs website lists the later but not the Marksman Elite. They are both 168GR OTM wih the same Muzzel velocity 2700 ft/sec.

Any difference other than the labeling? One new or older?
