Sako .408 ACP???

[MTSLW]

Picked up a really nice Sako AV and according to the barrel it's chambered in 408 ACP.

Curious if anyone has heard of this chambering or has any info? I bought it as a donor action / rifle but I'm a sucker for random calibers and might be tempted to keep it if I can find out a bit more. Plan to do a chamber mold if I can't figure it out and go from there.

Thanks!

Cheytac does make a 408 Cheyenne round. Not a super new cartridge but I've never heard it called the ACP. Could be a different beast all together.

Fine-looking hunting rifle, the AV, but I want no part of it if it is chambered in a CheyTac variant. That would hurt. A lot.

I haven't a clue about the .408 ACP.

Is the bore 408? What bolt face is it? Photos would be a lot of fun....
