Seen lots of complaints about this ammo with the bullets falling off of the cartridge and other issues
Seen lots of complaints about this ammo with the bullets falling off of the cartridge and other issues such as missing rounds as in missing one to 4 rounds in a box. Have thee problems been resolved yet, or are they still an issue?

Not Safe
I've tried these rounds in a FN PS90 (with 16inch and 10.4 inch barrels) as well as a PSA Rock 57. In the PS90, rounds would not feed properly after one fired shot. Every single time. Same PS90, same time, conditions, etc. FN manufactured ammo functioned fine. In a controlled test using the Rock 57, out of 50 rounds, 47 fired but did not budge the slide to extract, 3 moved the slide back enough with a portion of the casing still wedged in the chamber. 28 of these rounds needed a tap on the slide to fully seat the round. In comparison, a box of 50 FN manufactured ammunition, fired immediately after testing the Federal ammunition with the same firearm, functioned flawlessly. When measured with a caliper, a second box of 50, revealed a varying degree of overall length. Bullets were not seated firmly and with slight effort could be completely removed or pushed into the casing. Reading reviews written by others, it seems like a proper crimp would help this round, however, the extraction process is hampered by casings sticking. The high pressure this round produces is why FN adds a coating to the case; a coating that prevents the expanding case from sticking to the chamber and subsequently causing a malfunction. I have 15 boxes of these and a cursory check of them reveals that they all have the loose bullet seat and, while that alone makes them unsafe to fire, I would not expect these to perform any differently than the previous two boxes.

Ammunition Unsafe
I bought 3 boxes of 5.7x28mm and I had 2 rounds in a row where the bullet came out of the casing when “racking” the slide. I’ve never had this happen with any other manufacturer before and it’s scary. That makes them unreliable, unpredictable and dangerous. It’s a shame because only a few companies make this round.
