Hopefully , Marshall , and/or some of the expert crew can shed light on this .
There is a quiet revolution going on within the field of firearms ; that is generated by those who place high store on Lever Action Rifles , and the spirit of the American West that they symbolize .
It is , at once , a reawakening to the technical efficacy of fast handling lever action rifles ; and to the internal-ballistical advantages , of hardcast, big caliber, big meplated bullets .
As we non-engineer , non technical types try to tear and compare various hardcast bullet attributes , most of us stumble beyond "velocity" , "bullet wt." and "energy" concepts and try to orient on into Sectional density , Meplat size , and the ability of the bullet to break heavy bones , and penetrate .
Without getting all mathematical , and Phd. level in Physics , We could sure use a sort of ball park formula for those who fell asleep in Physics class .
Something like , " Well , in getting a handle on penetration , --- about 30% of it is the size of the meplat , about 40% of it is Sectional Density , and the last 30% is the weight of the bullet ! " ( Grabbed these right out of the sky , so don't throw rocks at me ) .
Maybe I'm trying for something that's got too many variables to be meaningful , --- but something like that would sure be useful in trying to select a bullet for a specific use .
This is getting to be the best Site in the field , Keep up the good work . ------ Highest Regards , MMCONCOLOR ( Old handle was MMCOUGAR ) .
