5.7x28mm – 40 gr GDHP – Speer Gold Dot (25728GD) – 500 Rounds

The 5.7x28mm has grown from a niche military cartridge into a mainstream choice for pistols and carbines, and owners have been asking for a proven defensive bullet in it. This listing is Speer Gold Dot 5.7x28mm 40 grain Gold Dot hollow point ammo, MPN 25728GD, sold as 500 rounds for home defense, carry, and owners who want enough of one load to test and keep on hand.

Gold Dot bullets are made by electrochemically bonding the jacket to the lead core, which keeps the bullet together and helps it retain weight as it expands. In a small, fast cartridge like the 5.7×28, that matters because light bullets can shed weight or fail to penetrate. The hollow point is designed to open reliably at 5.7 velocities from both pistols and carbines. This is a defensive load. For practice, a 40 grain full metal jacket or polymer tip load will feel similar in recoil.

This ammunition fits firearms chambered in 5.7x28mm, including the FN Five-seveN, FN PS90 and P90, Ruger-57 pistol, Ruger LC Carbine in 5.7, Smith and Wesson M&P 5.7, Palmetto State Armory Rock 5.7, and the CMMG Banshee in 5.7. A common question is whether 5.7x28mm and 22 Magnum are interchangeable because they look similar in size. They are not. 5.7×28 is a bottleneck centerfire cartridge and should only be fired in guns marked 5.7x28mm. Another common question is whether civilian 5.7 ammo is armor piercing. Sporting loads like this Gold Dot are not; the military SS190 penetrator load is restricted to military and law enforcement.

Speer 25728GD is new production ammunition, not reloads, made in the USA in Lewiston, Idaho. It uses brass cases with non-corrosive primers. This listing contains 500 rounds of 5.7×28 Gold Dot from one lot. Put at least a few magazines through your pistol or carbine to confirm reliable feeding, then keep the rest from the same lot as your carry and home defense supply.
