I have run all sorts of ammo through my 30 and have never had any problems. I've shot a 23 and If I limp wrist it in the slightest bit it FTF and as for brass hitting you on the face are you cross dominant? The only firearm I've ever had eject into my face was a Walther P22. But I would still the field strip the gun and clean it and inspect it thoroughly and check the extractor for sure. Let me know what the problem is and also If you try several ammo brands let us know which brands were the best.
