The TruBall Rifled Slug uses a simple plastic ball between the wad and slug to force extremely accurate results. It centers slug in bore, punching out as tight as 1.4" groups at 50 yards.


Revolutionary Truball rifled slug system provides the most accurate smoothbore slug. With the vast majority of slug hunters using traditional smoothbore rifled slugs, Federal set out to make the smoothbore slug more effective for the standard slug slinger. The TruBall rifled slug system is the result, and the most consistent group-to-group smoothbore slug on the market. With a simple ball that centers the slug in the barrel, we've reinvented and redefined smoothbore slug technology and expectations. See for yourself with 2 inch groups at 50-yards.
