Save it, and one day give it to your grand kids. Money come's & go's, heirlooms last forever.
Yes to this. Use an empty 30.06 case. The ones I'd worry about would be a little rougher in appearance. Think this was done for Korean forces on any scale. Not likely, but prudent.Have the chamber checked out or do it yourself..Someone told me that a lot of arisakas(t99) were reamed out to 30.06, bullet is smaller (.308) compared to the 7.7x58(.311) but was easier to find .06 than the 7.7 JAP ammo
