LP question

[Shane-O-Mac]

But I do have a chronograph, and did measure the velocity. That's how I know that I wasn't experiencing shoot down

Sorry. I wasnt clear enough. What I was reffering to was a chrono that measures FPS as your shooting a string. Another thing I remembered last night, was that if your using a LP tank on something like a mag, you will be running that reg at 90%-95% all the time. In a long string your practicly holding the reg wide open. Where as a HP tank reg will not have to work as hard. Yopu guys are making go back and try and remember all those old conversations I had with one of the engineers from AA when I teched for them.....................

That would be one that would read FPS on every shot? Do you have a chrono that will read the FPS on every ball at 15bps? If so what kind is it and where can I get one? Thanks.

Well I dont have one.....lol. AGD did sell there chrony with print out capablilitys, but otherwise they are pretty hard to come by. I wish I had one. My point is that with the measuring means available to us, it is hard to say, that your gun has no drop off/inconsistency. And standard gauges and ratings of tanks are not very accurate. I have seen just as many tank regs putting out 1000psi, that were supposed to be putting out 800psi. And that was using higher quality and accuracy gauges. So my skepticism about a LP tank that truely puts out as advertised, is well founded. Also, I never said it wouldn't work, just that it wouldnt work as well as it should, with the tank reg outputting 450psi. Shooting a string on an Emag with a 450psi input, may seem fine, but all the shots after the first may be lower fps (consistantly at a lower fps) than the first couple, thus giving the illusion of consistency/no drop off.

Bah, if a LP tank works for you, great. But dont buy one for a Mag............................

My chronograph DOES measure strings, as fast as I canshoot, and records the velocities.

What I'm telling you is that my Emag didn't show any drop off with a MacDev Conquest set @ 500 PSI output pressure.

Can you wrap your mind around that?

Why yes I can............................

Sorry for my skepticisim, I am used to people making claims without real data/facts to back it up, thats why I ASKED if you had checked it out that way, not to accuse you of making it up. I was just trying to find out if you had really checked it out properly. And as I said in my post after yours, it is highly possible that it worked just fine, no need to get smarmy (did I just use that word?...lol). But its all good, my opinion is that it isnt recommended to use an LP tank on a Mag. Your Conquest is a better reg than a screw-in also, so I would take that into account. Alnd I had asked you about the gauges, as that could make your tank look like it's putting out 500 when it is actually putting out 550, or even lower than 500, seen that happen with many tanks. They were tested with much higher quality gauges. Heres why I say that, the old AA Ashcroft gauges were about as good as you can get for a reasonabe price, and they are actually "Indicators" only meant to give an indication as to the pressure output/input (not as accurate as you might think). the mini/micro gauges were horrendous in accuracy, so thats why i asked about that.

Bottomline, I wasnt trying to be an jackass, just trying to point out how there could have been other variables that you may not have taken into account. I apologize if I offended you.......................

How fast can you shoot? If its 10 balls in one second your crony will give you fps on EVERY ball in that second? What crony is it and where can I get it? Thanks.

Oh ya Mobster got it right with this in the second post.

"While yes it can prob run that low, it cant run fast on that low"
