[QUOTE="ricka0, post: 77139, member: 3086"] goodgrouper - Awesome info (as normal for you). What you report is also consistent with the physics - a flatter pressure curve means more time at peak temp (which implies peak pressure) - therefore you get much accelerated barrel/throat wear. It's heat the moves the bullet, your not firing an [url="http://www.alka-seltzer.com/as/experiment/student_experiment.htm"]alka-seltzer gun[/url] [img]/ubbthreads/images/graemlins/smile.gif[/img] BTW, my propellant chemist pal leaked the engineering memo that marketing started with [ QUOTE ] <font color="purple"> Although these new powders have a higher energy content, they do not cause [b] <font color="red"> [4 times ] </font> [/b] greater wear to the gun [b] <font color="red"> [They only cause 2.2 times greater wear ] </font> [/b] .
