Having to choose between Lyme disease (shooting outdoors in abandoned areas with overgrown grass) or taking the airguns to the range, I'm going to the range now.
Questions: I have a Great White and guppy (both 4500 PSI) that I can take to shoot at the range. My approach is to leave the tank in my car and refill from there.
I want to make sure that I am not missing any safety tips. Assuming late summer temperatures in the mid 70s to mid 80s, is there anything I should do about fill pressure, securing the tank, etc? Should I fill the tank to less than 4500 PSI to prevent summer-heating from over-pressuring the tank? Do you guys keep your tank in the trunk or in the cabin of the car? How much of a risk to the tank is regular rolling around and bumping in the trunk of a car? is there a recommended way to secure the tank so that it doesn't get dangerously bumped on the drive to/from the range? (Or is this not a big concern?)
...I feel more comfortable with the tank at home, and I just don't want that tank going off like a rocket in the car. I see guys like Tof hauling all over the desert with these tanks, so maybe I'm being too cautious.
Any tips or suggestions...?

Fire fighters carry them into burning buildings, run into stuff while working and never sweat it.
CF HPA cylinders are VERY tough ... treat with respect and don't be stupid with one you have no worries as described IMO.

Yeah, I wondered the same thing but I think the burst pressures are usually like 19Kpsi+ or something on those CF tanks aren't they?
I think you could put it in your oven on full blast and it wouldn't burst. Purely illustrative, for obvious reasons do not try this ;)
You can probably figure out specifics - search for Gay-Lussac calculator.

Secure them so they do not roll or slide around. Bottom facing forward is best just in case of a sudden stop. Most likely damage is to the threads or manifold / fill station. I have spent endless hours researching CF tank failures and most are due to damage of the threads and or the tanks neck.
SCBA tanks / breathing rigs are worn with the neck down and this provides better protection to this more fragile area I would think.

I have seen vehicles fitted with a bracket/cage type holder for Nitrogen tanks (racing applications and off road too.) I would feel comfortable using something like that for securing an air tank in the trunk of a car or the back of a pickup. The bracket/cage could not be near as expensive as paying for the damage an unsecured tank could do flying around in the case of a collision.
Be safe, guys.

Assuming late summer temperatures in the mid 70s to mid 80s,
That sounds great, it was 106 here yesterday.

Thanks for the advice everyone...
