Ted. The bullet in a SAAMI spec round needs to have .020s jump to the lands in a SAAMI spec chamber. If it does not it will cause pressure problems. The throat in most, if not all, liberty barrels is short. If you reload and seat your bullets deep there is not a problem. In my mind every barrel shound go back and have the throat reamed so factory ammo keeps to the pressure limit of the Grendel.
