twist rate

Well, that certainly is a significant difference in ROT within one manufacture. I took a look at the T/C site and actually could not find the Icon listed in 7/08. I did see the Venture chambered in 7/08 and the claim of 1:9" twist rate.

I could not find any numbers for the rate in either the regular Encore or the Encore Pro Hunter. I certainly find it odd, as you do, when most all the commercial loads available for the 7/08 are in the 140gr range with only a couple 120s available and 1 each in 150 and 168gr, to have such a big difference within a single manufacturer.   Huh?

I have no idea why there is a difference, perhaps a typo.  Call T/C, they'll answer your questions.

You have it reversed, the faster the twist for heavier bullets, slower twist for smaller bullets.  While I don't know the precise recommendations for weight/twist in 7mm-08, it seems 1:9 would be for 140gr and heaver, 1:12 for less than 140gr.
