The CCI 22 Maxi-Mag TNT is a high-velocity 22 Winchester Magnum Rimfire load built to take varmints down fast, and the 30 gr TNT jacketed hollow point is the reason hunters and range pros trust it; launching at roughly 2200 fps and delivering about 322 ftlbs of energy, this Maxi-Mag TNT round flies flat with minimal mid-range rise, expands explosively on impact for clean terminal performance, and retains the match-grade consistency shooters need for reliable accuracy at longer rimfire ranges. If you chase prairie dogs, ground squirrels, or need a potent pest-control option, the combination of the TNT bullet design and CCIs proven priming and brass gives repeatable point-of-impact and predictable expansion at extended 22 WMR distances. The cartridge runs well in bolt, single-shot, and semi-autos chambered for 22 WMR, and its brass casing and hazard-aware packaging make it practical to store and transport; made in the United States, the 22 Maxi-Mag TNT is the sub-brand choice for precision varmint work and high-velocity small game applications.
