Hmm.......I am not sure I follow the math and it probably does not work that way, but I think I follow the general gist of things. I do really appreciate all of you posting on this issue.

Based on all of your observations I am more than safe on psi, and I was going to go to lower psi for protection of wood. But it sounds like lower psi is not necessarily lower recoil.


Any comments on poly-wad Vintager shells and actual recoil, or pressure? I know they have 25g shells that are about 6500 psi.
