Varmint shooting requires a accurate bullet built to deliver energy fast. Speer® TNT® hollow points meet those requirements, and at a popular price. The .224" 33 grain TNT uses different construction features tuned for the 22 Hornet cartridge, like a pure copper jacket, a larger hollow point with aggressive notches, and a special base to accommodate Hornet rifles with both .223" and .224" diameter barrels.
