Anyone out there using a Stoney Point headspace guage for the new short magnums? I’ve gone through their website and don’t see anything for the 270WSM. I’m in-process of getting my gear to start reloading, so may be missing the obvious. Perhaps the 270WSM uses one of the existing bushing sizes and simply isn’t listed specifically.

You don't want to buy one thier cases anyway. Send them two fireformed cases if you plan to neck size. And if you don't necksize, you can full length size the case after they modified it.
One tip with the Stoney point. Be sure to use a dow or something to give pressure to the bullet while finding the rifling. This will increase your sensitivity and consistency by 3 fold.

I had to call them and they offered the case just not on the website...I would send them fired cases like Big country said. I understand the new unit has a stiffer rod in it the old one was maybe a bit flimsy.
