FN SS197SR is a 5.7x28mm sporting load built on a brass case and topped with a 40-grain Hornady V-MAX bullet, the polymer-tipped ballistic design made for accuracy and controlled expansion. FN lists the muzzle velocity at 1738 feet per second, and fifty rounds come in each factory box.

In Delaware this is a cartridge for paper, competition stages and varmints rather than a bulk plinking round. The light, fast bullet shoots flat for its size, and the tip opens on impact, which suits small-pest work on open farm ground and target sessions where a quick second shot matters. Brass cases also make it a sensible choice for anyone who keeps their empties. Use it in any firearm chambered for 5.7x28mm FN.
