It has run great in my pistols with no noted durability/wear problems LOTS of rounds later. I keep an eye on the extractors just to be safe but haven't had any issues. It is filthy stuff though.
I think you should buy boat loads of it and if it doesn't run in your 17/34, you can give it to me.
On topic, I've had no issues with wolf pistol ammo on any number of cheap unhardened steel targets. And I've got 5000+ rounds of 223 Wolf on an Action Target torso with no visible damage, but the torso steel is the 550 brinell model so YMMV with softer steels.
