A interesting find Olin Winchester Dummy Cartridges.

[The.22guy]

Came across these Winchester produced action proving rounds a while ago and just thought id share.
Kind of neat as they have a real bullet as apposed to the other makes that are just one piece.

Does anyone know when they stopped making these ?

I don't know about the Olin stuff, but Brownells still sells an equivalent product.

Inert, Factory Spec Dummies Give Safe Function Testing

Manufactured to exact specifications, including diameter and length dimensions, weight and balance of factory loaded ammo, these DUMMIES have the proper functioning characteristics to reliably check magazine feeding, action timing, extraction and ejection of all guns. The only professionally accepted and safe way to check gun functioning; live ammo should never be used except in actual test-firing on the range - after you have checked the gun with DUMMIES. The very reasonable cost per DUMMY is an added incentive to use them regularly. The blackened case makes them distinct, and instantly recognizable as DUMMIES, which makes them ideal - and safe - to use as a sales aid. Especially useful when demonstrating how a particular gun functions or in gun safety instruction classes. They absolutely eliminate the chance of an accidental discharge.

Cool find.
Is that a kling-core soft point aka KSP ?

I've got some olin dummy rounds in 40 S&W still in the factory box.
Must've been for Police agency's.

Cool find but they look almost too real to me. I prefer a brighter colour or fluted sides to tell them apart easier. Noveske makes some ammo that is entirely black for example.

I have some in different calibers but mine are all black .
