Me too...

But you say the kick back (impulse) has little bearing. All my limited teachin' tells me that more mass in the barrel (heavier bullet) can bring pressure higher. More pressure, more kick?

Is that wrong. I was a cop and security consultant now, so I ain't no scineterst, so explain to RK and Ed's level [img]biggrin.gif[/img]
