One thing I forgot to add, don’t discount black powder for reloading these rounds. I recently shot some BP reloads, and they work for CQB out to 100yds. Yes, accuracy will suffer, you may have to hand cycle some loads, and the smoke will give away your position, but anything is better than nothing.
My local shop is having trouble finding Wolf, but no problems finding Federal Fusion, Winchester, Red Army Standard(Romanian), or any of the local reloaders.
Never challenge a man who has nothing left to lose.
