Weatherby Mk.V twist rate?

Dear all,

could you perhaps help me with this:

is it possible to identify the probable barrel twist rate from its serial number?
I own a 7 mm Wby, which just does not stabilize the bullets.

The serial number is H 240 8xx. It has been made in Japan. I was told the older barrels have 1:12, whereas the newer have 1:10.

Thanks a million

you can check the twist rate with a cleaning rod

Biggest fail of 2014 so far...

My guess on W3P .308 230 Grain Bullet: G1 .740-.755
