I run a low-pressure regulator after my main regulator as well. Drop it to 50 psi with the main, 10 psi or so with the low-pressure. I've never experienced end-of-tank dump. I don't even know I'm out until my drop checker doesn't change.

Only other possibility is that I use a 50# cylinder, don't know if that would matter. I've never used a 10#.

Okay...so I exchanged my tank however the pressure valve shows 650 which is a lot less than what my previous tank shown. Does this mean they might have exchanged for a tank that wasn't really full or does the pressure not really mean much?

Wait for it to reach ambient room temperature. It should go up.

Good link.

You can use a good dual stage CO2 regulator and run the CO2 cylinder until it is empty without "end of tank dump."

Where I get mine fill they put it on a scale and weight it when it was empty and when it got filled wrote down the weight under the tank so all i have to do is put it on a scale and check it

If you're shopping for a new regulator, single or dual stage will make a difference in price - not huge, but there will be a difference.

If you're perusing the used offerings on ebay, it's nearly a orange/purple popsicle type distinction.

There are good 2 stage regulators on ebay for cheap on any day of the week, the tricks are to know what brands are good, and to buy from someone who knows a good regulator from one that is dead.

TPT included LINK details some Victor models, prices, what some units were stolen for on ebay etc. etc.
