From the Pykrete website we find this quote:
What is the math error here? If this was true then the converse is true that a .243 bullet could knock a 1000 pound object a foot. Or a hundred pound object ten feet. We obviously don't have .243 rifles blasting holes in backstops and knocking down their shooters. So what is the REAL force and how is it calculated?
I sem to remember something in the dim recesses of my memory of foot pounds per second squared.
Both were shot with a .243 rifle at 100 meters. A .243 bullet fired from 300 meters can push a 1 lb object for a distance of 1000 feet. Remington Catalog lists stats for a .243 bullet: 243 - 100 gr bullet 1,945 ft - lbs energy .30-06 - 150 gr bullet 2,820 ft - lbs energy .300 Win mag 150 gr bullet 3,605 ft - lbs energy
