For a day hunter, the paper cartridge is a viable loading method. Paper cartridges for a woods walk where the targets are scored by impact on a steel plate, then the paper cartridges would speed up loading of subsequent shots. For target shooting where precision placement of the impact on target for score is paramount, then individual loading for each shot is needed.Because I prefer to use materials available in the period of use, thus ruling out plastic tubes. Of course wooden apostles, or river cane tubes could be used. Really in period they would have used a horn, there’s overwhelming evidence of that. The context of the paper cartridges I describe is for a day hunter, or target match. Our club trys to discourage the use of plastics as a matter of common agreement. Not policy. BJH
