I was pretty sure I have reloaded the extrema brass, as regular brass no extra steps. I had some boxes of a buddies factory once fired, so I one shot lubed 15 and setup my RCBS comp fl die. All 15 decapped and sized normally, then I primed a few using BR4 primers with the RCBS press priming arm. Primer pockets measured 0.124, the CCI primers are 0.120. I looked through my reloads on the shelf and found a box of extrema reloads, that I have shot 20 or so. With sale price under 25.00 sometimes, don't think I would process. But I have done 50 before without issues.
