I kind of agree with you on the RPMs but how in squat am I gonna hit the media 100% dead center every time at a distance giving the appropriate velocity?
I have developed the process to the point were those three shots were made in 45 minutes including 2 trips to the house for reloading and a phone call.
Put the media at 1 mile and this little old man ain't gonna hit it plus the time involved is prohibitive.
When I added the moisture to a more appropriate level the penetration was straight with appropriate expansion for the velocity.
Wish I had more answers than questions.
The process however seems to be a step in the right direction.
