APEX Ammunition Waterfowl TSS shotshells are made from 18.1 g/cc density tungsten alloy. Tungsten Super Shot is a versatile and hard-hitting shotshell pellet that’s denser than lead (11.34 g/cc), bismuth (9.8 g/cc), copper (8.8 g/cc), or steel (7.84 g/cc) — allowing the use of smaller-sized shot and significantly more pellets than other shotshells (No. 9 TSS compares in energy to No. 4 lead). More pellets per ounce means a more powerful payload with higher pattern density and superior knockdown power at extended ranges. TSS is also highly effective in sub-gauge shotguns for those who prefer hunting waterfowl with 20-gauge or even 28-gauge guns. MSRP: $49.99/10-round box. Contact: www.apexammunition.com
