Some of us have to go backwards, I have a project laying in the shop that requires an .318 cal 8 MM bullet., A Cal 8 K, (8 X 51). Though it was a hunting round more then a military.
Problem I have is the Action is a Mannlicher-Schoenauer. The cal is on the on the action instead of the barrel, so I have to match the barrel instead of matching the action to the barrel.
Good .318 barrels are hard to find, but I think it will be worth it in the long run. I have the reamer & headspace gages (which are a tad differant then the 308 case so I couldnt use the 308 gages).
Then I'll be in the market for .318 bullets so pull them and send them to me
