Gamehawker, welcome to the Brotherhood of the STW! The x- dies, work just fine. I have a set of them for my seven mag, and they work just fine. Just set them up as per directions, and trim your brass .020' or in your case, trim them to 2.830. The die takes care of the rest. As far as brass goes, it is few, and very far between, I have about 200 plus pieces of brass, including some premium factory ammo that I bought from a guy that has sold his rifle. I have 3 rifles in this caliber. You can form them from 8 mag brass, which I do see often in discount fliers. Also try gun shows, and the classifieds here. Let me know when you are ready to load. I have some great formulas to get you started. There are a lot of STW shooters on here as well. Good luck, and don't give up! AIM SMALL, MISS SMALL.
