7.62x54R Wood Bullet

Can anyone ID the 7.62x54R with the purple wood bullet? Headstamp is “188 45”. Was this made by the USSR or did Finland or someone else reload it as a blank? Any help appreciated.

I would need a better look, but there were some similar blanks floating around the US about 2 years ago, made using Israeli 7.62x51 “bullets”. I have another that was reported to be Czech. Can you post a close look at the case mouth?

Like this? I just compared it to my single specimen of the Israeli 7.62x51 purple wood bullet and they look different. I’m not sure if there are other types though…

Nice pic. I’ll compare it to my Czech round. I don’t believe I kept an example of the US-found one.
