Ah, that makes more sense then. An obvious overfill….you should get a scale and weigh the tanks after filling. You need to read tenths of ounces to a couple of pounds. I write the empth weight on each valve body.
I’ve got a couple of ‘postage’ or ‘Diet’ scales that do this that cost me $25 or so but also just got this one, really neat:
Very neat little scale, goes to 36 ounces, IMO cheap insurance. Even if you don’t fill your own (like a lot of us do), you know from first hand experience sometimes the shops are happy to give you a little more than you paid for. The key is to find that out and vent the extra before it warms up (I used to take the scale in the car and weigh the tanks in the parking lot before I got my 20# tank (which is also recommended). I got two overfills out of several dozen over two or three years. All from the same shop, the same guy did both overfills (they don’t weigh……).
Yes, PB safeties are pretty common, most shops will have them. I see them at 1800 psi, sometimes 3000. They’re easy to change out (I’ve bought tanks with blown ones and one that leaked there), a couple of bucks each. You might try the shop that overfilled your tank, seems to me they owe you another safety and a free fill?
Good luck and good shooting.
