Thanks all for the information.
I thought I’d pull the rds to see what I’ve got. These rounds have in the past been inerted so it’s possible that the bullets are from elsewhere.
Neither bullet has a core ???
The left hand bullet dia is 7.90mm and the hole for the core is 3.57mm, the bullet is stained/blackened all over.
The right hand bullet dia is 7.83mm and the hole for the core is 4.29mm the stain/blackening is patchy.
All the 30 rds on the feed strip are stained/blackened, some rds have a pinkish casemouth seal.
All the rds weigh the same give or take a little so I don’t think any bullet has a core to it .
Any thoughts Gentlmen…
