I tend to see things in black and white. There is a life span on these bottles. That life span was put in place for a reason. It’s not worth the risk to me.
The way we treat our bottles, it would be easy to justify extending that life span… They’re not abused, always cared for, never in any hazardous environment, not knocked around, not stored in extreme temp changes….
I have heard that Europe uses the same bottles for 30 years but, I can’t confirm it. I’ve also heard that if you hydro on year 14, you can scratch another 4 years out of the total life span.
Treat them like bombs. There is a lot of potential energy stored in those bottles. Err on the side of caution. You might not be shooting at all if you get injured.
That’s just my 2¢ on it.
