I use powdervalleyinc and wideners for all my powder and primer components for for rifle and pistol shooting. IMHO, it might be a good idea to try Wolf primers. They are readily available right now, where few if any vendors can keep a good supply of cci, win, fed, etc. in stock. A couple of points, use the Wolf small rifle magnum primers, not the standard, the magnums have the same charge, but use brass cups instead of copper.
The pistol primers are excellent, and $19.
Buy a bunch of what you will use, and the hazmat fee breaks even very fast.
