Sauer 100 - Talk me out of it

[Q_Sertorius]

Ouch, sorry about that. That's your 9.3?

No, it's the 6.5 CM.

The 9.3x62 only has 10 rounds through it so far. Small sample size, but it is stacking rounds so far.

That's wild, and hopefully a one off that gets resolved quickly and easily. I'd have assumed it was your 9.3 like others mentioned. A cracked stock on any 6.5 is concerning.

65 in-lbs with paint pen on the threads seems to be working fine so far for me.

Did exactly the same, on 4 different Sauer 100s so far. All sling lasers.

I had mine at 60 on the 6.5 CM. I don’t think that 60 contributed to the stock cracking.

If anything, apart from a flaw in the wood, I am inclined to blame some of the factory ammo. Some of the S&B factory loads had some slightly hard bolt lift. The Fiocchi 129-grain PSP had some hard bolt lift and extractor marks. I noticed that the day before yesterday, but since I wasn’t going to use them again, I didn’t think anything more of it. I have a hard time believing that a factory load in a 6.5 CM would crack a stock absent a flaw…

I left it alone on the 9.3x62 (I just haven’t bothered to tinker with it yet).

But that's the same wood stock that they put on all their other 100s right? I can't imagine overloading a 6.5 Creedmoor enough that it could match the recoil of a 30-06, let alone your 9.3. I think you're right, I'd bet flaw in the wood, especially for that location.

Sorry to see your issues. I don't think your problem was the ammo. It looks like your bolt was making contact with the stock and not allowing the bolt to seat fully in the downward position. The hammering of the bolt on the stock cracked it. That's my $.02.
