I was a consultant on the Northern Toole County Bowling Ball Mortar Project this past. This project was conducted as therapy for a couple of senior citizens trying to adapt after a transition from a lifetime of work and toil, to a life of retired leisure.
Ballistic models will not accurately predict the reults that are acquired from actual firing. No two bowling balls are the same weight nor have the same finger hole pattern. Windage will also very from day to day from air temperature and different results will be achieved with all other factors are the same.
We found it best to start with a small charge and work up. Make a notes about each ball when you fire; weight, charge weight and range. No two will shot the same.
Word of warning. If you intend to fire a bowling ball as high and as far as you possibley can. Think real carefully about where it is going to land. I can tell you from experience when the ball goes up and out of sight, and you no longer know where it is going it is scary!!!
Fire it where can see for sure in excess of a mile and you can see the flight of the ball from muzzle to impact....you want to be absouluty sure beyond any doubt that there is nothing that can be hurt or injured from that ball.
If you are firing off into the trees and you can not see the actual impact zone, you are careless and negligent and give us all a bad name.
Impact zone being the area where the projectile impacts and comes to rest!
