I have a Deviant Hunter and an anTi, both 700 SA length, and both chambered in 6.5PRC. Have yet to have an ejected case (empty) hit the windage turret of the either scope. That said, both rifles have Swaro Z5i3.5-18x44s mounted in Leupold Backcountry rings. - Lows on the Deviant Hunter; Med on the anTi. As JCMCUBIC pointed out bolt handle clearance on the anTi (at least) is more of an issue.
FWIW, I concur with Burleyboy on the more open action of the Defiance vs the Bighorn (Zermatt) Origin. Had an Origin action and sent it down the road in favor of the Devaint Hunter.
On another note, the Tenacity seems to be held in pretty high regard amongst the PRS crowd. I suspect that if there were issues with ejected cases hitting the elevation turret, this is where they'd likely show up, given the turret size on most of the scopes in use on the PRS circuit.
