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.
This also makes the case (pun intended) for careful inspection
of all brass before you load up.
Also for wearing safety glasses.
You knew the history of the case and
still had a problem. I have had NEW brass improperly
annealed at the factory that failed on the first shooting,
-even on low pressure loads. The factory replaced them.
Bob, a friend of mine told me if you don't have a
comparator to measure headspace of the
unsized, fired brass, you can do the same thing with a
bit of tubing or a socket that fits over the neck and
against the shoulder so
you can measure with your caliper and compare to factory
brass. Also you could cut open one case from the batch
and measure above the web to see if there is any thinning
which could lead to separation. A micrometer is best for
this.
Toss any that are questionable.
As Nosler says, ALMOST anybody can reload. I learn
something everyday.
You may even find a friend's rifle, like that old -03,
that has dangerous headspace and save them some grief.
Brit 303's are notorious I have heard for excessive
headspace.
