Winchester 70HV 223 question

[Big Dog Dad]

I have a newer Winchester 70HV in 223 and was wondering if anyone knew what the twist rate was for this chambering in the factory heavy barrel. I know I can get out the cleaning rod and check it that way, but it is a lot easier if I can just type this on a forum with the great amount of knowledge found here. Thanks in advance.

Probably 1" in 12" or 1" in 14". The heavy barreled varmint rifles usually are used with 45 grain up to 55 grain bullets which stabilize best with those twist rates.
