I have a 12 year old daughter that is really getting into competitive shooting and wants to try out 3-gun. The only thing we don't have is a way for her to carry shotgun shells that allows her to reload quickly. I have seen carriers made specifically for this purpose, but they seem to cost more than $60 a piece. Does anyone have suggestions as to alternatives in either style or brand that will make it more affordable. She will duct tape a zip-lock bag to her waist if need be, but I know those of you with experience have some ideas. Thanks
