Pro Pouches are rated at 300-350 ft per second. New latex formula makes them easier to shoot and more stretchy! When you want to inflict the most damage, this is what you want! Users will typically get between 200-400 shots off with the Pro-pouches using 1/4 inch or 5/16 steel before having to replace them. * Pouches will be stiff at first but will loosen up after 10 shots or so.
