You can download the 2019 catatlog here that mentions some twist rates. I don't know if Mauser made any changes for 2020 but @troy fairweather mentioned the 1:8.7 twist for the 6.5 CM which is consistent with the 6.5x55 twist shown below. It seems highly likely that the 6.5 PRC has the same 1:8.7 twist. The two 6.5 PRC Proof barrels I'm picking up soon have a 1:7.5 twist. I simply don't understand why a manufacturer doesn't do some freakin' research and provide appropriate twist rates.

Hmm I'd looked around their website and hadn't seen that.
Those are all a little slower than I'd like.
I might go 7mm RemMag, but even that twist is a little slow.
Although considering I'm looking for a rifle for coyotes and deer, not Elk and bear the twists should be fine.
