Just got thru loading a few rounds of ammo for this rifle after my brass & dies came in. Tried to chamber loaded rounds but bolt wouldn't close. Noticed then that someone has severly dented the end face of the barrel/chamber. I could smooth out the protruding damage but that would leave me with voids that I don't trust. Looking for a replacement barrel & havn't been able to locate one. Any help would be appreciatd.
