NEVER,EVER pick up range brass! You simply cannot know it's history and are rolling dice it won't have a catastrophic head seperation or case rupture.A brand new, Federal ( thickest case out there) from a rifle with excessive headspace will seperate after resising and firing.I know,I had to extract the shell from a Garand when it was reloaded after firing in an old 03 Springfield!!! We practise firearms safety to the point of almost silly failsafe handling ( don't we?)

Now, as to HIND helcopters. I refer everyone to my favourite buggout movie Lonely Are The Brave with Kirk Douglas. Old Kirk shoots down Bill Bixbie with a .32 Winchester.My helicopter rifle is a .375 with hunting solids rubbbed in garlic.
