I am messing around and have made a shotgun slug
I used a CSD wad and spacers
CSD wads are a thick steel shot wad that is not slit when you buy them
Added a pressed in cast bullet that is just over the ID of the wad
So I made a non discarding slug that I plan on shooting from a rifled 870 shotgun barrel
Total weight other than the wad is 3/4 oz
Anyone have any load data for a high velocity 3/4 oz load ?
I know I will have to adjust for the CSD wad
But a friend has a 870 12 gau barrel with a pressure gauge attached to it
So I can make sure the loads are safe once I have some place to start
I would like to be in the 1400 to 1600 FPS if possible
Thanks
John
