I am a new member as of yesterday. This is my first attempt to communicate on this sight. As I purchased my 8 mm Giffard, without reconditioning co2 cartridge I am getting about 370 ft / second with a 3.15 round ball. instead of rebuilding the original cartridge I would like to leave original. I see there is a 8mm buxton conversion for my Giffard. I would be interested in plans, diagrams or kit all ready to go.
Thank you. Calvin Moser, South Dakota.
