Using a Stabilizer on my Tac-1

[Argelmcgee]

Here's the deal. I have two tanks, my old PE 68/4500 and a newer Crossfire 68/4500. PE tanks, as you probably know, are factory set to ~850 psi, while Crossfires are set to ~800 psi. I have my Tac-1 tuned to shoot with the Crossfire, and I'd rather not mess that up, or worse, start shooting hot if I can't re-chrono. I'd like to be able to know I can just screw either tank into the ASA and get the same results. So, with that said... I don't shoot fast at all, the most I really do are bursts at around 12 bps when I'm feeling trigger happy. I'm almost positive that my Stabilizer will keep up at 800 psi. If I do this, my PE, which is more inconsistent, can be screwed into the ASA in the field, and I don't have to worry about the velocity or anything being off.

What do you guys think?

When shooting your burst you might have a bit of drop off using the stab. I remember Palmers saying when running dual regulators (which you are doing with compressed air) that the first regulator (in this case the tank regulator) needs to be around 200psi higher then the next one in the series in order to prevent shoot down.

If you already have the stab I'd say try it and see what happens and play around at the chrono. It might end up being easier to just re chrono when you switch tanks.

you switch tanks, velocity will should still be the same.

Why are you using the Stabilizer? Your 'mag already has a great built-in regulator, there shouldn't be any need to put another reg on it.

Output pressure of the tank should in no way affect the velocity of your shots - the only thing affecting that is the pressure and volume of air in the chamber, and your reg will keep that constant so long as it's being fed enough air (anything over 600psi should do the trick, even lower theoretically). Tank output pressure shouldn't affect anything but your recharge rate, and both of those tanks should be more than sufficient for 12bps.

That being said, double regulating could hurt the recharge rate of your 'mag. Shoot a string and bring it over the chrono as you do and compare that to your first shot. If it's significantly lower, ditch the Stab and see if it improves. Again, there's no need for the Stab on a 'mag unless you're shooting CO2, which you shouldn't be doing on an X-Valve anyway.

Thanks, ThePixelGuru. I gotta get out of this Tippmann mentality, I keep forgetting that Automags regulate velocity with a regulator... Gawd...
