Standard pouches are designed to be the most durable but must be replaced after a period of use. We look at them like disposable razorblades-it's a good idea to have a few extra around. Standard pouches are rated at around 275 ft per/sec. Users will typically get between 300-500 shots off with the standard pouches using 1/4 inch or 5/16 steel before having to replace them. NB: Pouches will be stiff at first but will loosen up after 10 shots or so.
