twist rate cz zkk 602 in .375?

Gents!

I am wondering if my old (1985) cz/brno zkk602 has the 1 in 12" or 1 in 14" twist rate?

I would like to try the heavier (350-380gn) Woodleighs or Rhino bullets but do not know if they will stabilize.
For the moment I do not have access to my dewey rod so I cant measure it at home.

Sincerely
Daniel

Thanks!
I think that I can abandon the idea of shooting anything heavier than 300gn in that barrel then.

I have read that a 350gn bullet requires a twist of 13,2 to stabilize, and if that is correct then the heavier bullets will not be stable.
