Ballistic Products Maxi Nitro Card 12 Gauge .125" Thick 0.740 Diameter 500/Bag

Nitro cards are used as a seal or space between the powder and the plastic wad or directly underneath shot. They can be used in place of a plastic shot cup in many retro-style and English game loads.

Many modern load designs use nitro card wads inside the base of the shotcup to adjust the shot column height (for proper crimping). Nitro card wads are die cut from specialized industrial board materials. These materials are specifically selected and tested to withstand the tortures of expanding propellant gasses and heavy payloads.
