I am wondering about pressure (and subsequent velocity) of a variable in an otherwise identical shotload.
If one uses a tight fitting over powder "nitro" card and gets 'X' pressure/velocity.......
......What can be expected from using one tight fitting over SHOT card atop the powder charge in terms of pressure/velocity?
What if one uses just a tight fitting cushion wad atop the powder charge?
Assume all else in the load is equal.
Thanks for your thoughts, Skychief
PS: I want to think that a load with a thin overshot card or just a cushion wad wont seal as well as an over powder "nitro" card and develop less pressure/velocity as a result.
Don't let my suspicions skew YOUR thinking as I may be all wet. Possibly any of the 3 will seal as well as the others.
Maybe someone has tried this variable out over a chronograph. :idunno:
thanks again for sharing your thoughts! :thumbsup:
