Does not feed - Hornady Critical Defense 5.7x28mm 40 Grain FTX Brass Cased Pistol Ammunition

I own a Smith & Wesson M&P 5.7, and despite doing everything Hornady recommends, the bullets do not feed in my pistol due to the blunt nose. Plastic-tipped bullets like the FN with Hornady V-Max work fine. I use critical defense ammo in all of my other pistols. They work great in all but the 5.7X28.
