At the current offering price of 18.99/50, I'm torn on recommending them as we can consistently get factory Fiocchi for only 1-2$ more per 50. These loads are at the mercy of the 1X brass they are using. Coating seems to have been ablated a bit vs doing the tried and true Simple Green/water washing method. Some of the primers walked out during firing which usually indicates the brass has been through more than a few reload cycles. One body ended up split, which I've never seen before on 5.7 FN brass.
I still wish companies would crimp 5.7 loads to prevent set back. Even with these longer projectiles, there were 1-2 instances where the P90 mags caused a miss-feed, and shoved the bullet back into the case. I wonder if that's the reason the SD/ES on the P90 results were so high.
