Quoted:
<snip>Here is my logic: it is once fired brass by someone who does not reload. If they reloaded they would have picked them up. Therefore, it was factory loaded ammo and only fired once, so how bad could it be?
I say this with courtesy and respect: your logic is flawed.
I reload. I pick up as much brass as I can find. However, I don't find every piece of brass I shoot. Just because someone reloads doesn't mean they
always pick up the brass they just fired. If it is laying on the ground it is not always once-fired.
That being said, it doesn't really matter if it is once fired or 5x fired. You aren't going to have problems if you inspect your range pick ups for problems like split necks, flattened primers, loose primer pockets, and other indicators that the brass may be ready for the scrap bucket.
Someone may post the link where the guy fires the 40 S&W brass a bunch of times in a row. I think it was like 40+ times before he felt it unsafe to proceed.
