This a chromed non-magnetic case with a turned green aluminium projectile.
A shallow primer pocket has no flash hole. It has a segmented 7 0 027 hs and 2 deep cannelures part way up the case
In fact it looks like the other Swedish dummies around… except…
The cartridge has a double shoulder so that the case chambers in either a 7.62x51mm or a 6.5x55 chambered rifle. Is this a common round and are there any other similarly designed dummies?
