FN 5.7x28 SS197SR Ammo 40 grain V-Max Box of 50 Rounds 10700017 - Online Only

The price is a little high but the ammo is perfect for a self-defense rifle.

Will be ordering again

I have always been interested in 5.7 x 28 mm ammo in general and the FN 5.7 pistol in specific. I just purchased the Ruger 57 recently and am very pleased with the pistol. With 20 rounds in the magazine, an all steel slide and a highly visible front sight it is a very well made firearm. The ballistics on the 5.7 cartridges are very flat and high velocity compared to 9 mm and .40 S&W cartridges and the soft points of the SS197SRs make for excellent expansion and tissue damage when combined with the extreme kinetic energy. All in all, I am very impressed with FN's design and evolution of this round. My only wish is that this would become less expensive in the future! (wink, wink!)

The ammo itself is great. No complaints in that area website gave updates as often as possible. Only issue I had was UPS delivered it, they are supposed receive a signature to drop it off which wasn't done. When I opened the bag it came in the box of ammo was ripped and rounds were all out of the box, no damage to rounds though so that's good.
