10 ga paper hulls and card wads

[Reinhard Geisert]

I have a large number of never loaded 10ga paper hulls and also over powder card and fiber wads.
I would like to load them with low pressure loads for an L C Smith with twist barrels. 19 grains of Red Dot with plastic wads and 1 1/8 oz of shot is the normal low pressure load.
My question is with card over powder wads I know that I will not get as much velocity as with a plastic wad. I also believe I will get lower pressure, does anyone know much lower velocity would be, and to get velocity up if too low, would an increase of a grain or so of powder get velocity and pressure back?

You'll be just fine with the load you listed. I like that load except I use just 1oz of shot. You'll need some more cushion wad height then. Load one or two up and test them. Use Charlies' method - will it knock over and penetrate a Dr Pepper can ? You can get more wads from www.circlefly.com
