500 Gram grand finales

500 Gram Grand Finales are the largest consumer fireworks devices available to the public. Ranging from shots of nine (large caliber racks) all the way to 500 shots or more (criss crossing zippers), these devices are generally used as the culmination to any consumer fireworks show. The less shots a device has, the more power each shot contains, but less action (500/# of shots). The more shots, the less power, but more action.
