Calling all regulated AEA challenger/pro owners

Oh, I thought you had a Challenger Pro. So it's a regular Challenger with the regulator upgrade. (nice)

Yeah this makes it a little more tricky to adjust. I could help you guess but it's a little risky if the regulators are different. I would suggest asking Bin or whoever you bought it from... "what pressure do the regulators come set at, and how much is it safe to adjust"

Then come back and let us know so other people searching for that answer have it archived here. If you'd like I can ask him for you... but if you bought it from someone else it could possibly be set up differently or to a different PSI than BinTac has them.

If you could that would be great. I don’t know who bin is or for that matter know how to reach him lol
 
So I’m gonna do 2.5 turns to to get roughly what I want since I can’t be as precise as I’d like. This IS correct right?

You are very far off and doing that will probably blow your regulator. Please review prior comments but ultimately do precisely what Bin tells you. Like I said earlier if this regulator works similar to the one in the Challenger Pro, 1/4th of a turn makes a very large difference. You want to turn it like 1/8th at a time or less usually.

Silver, if 1/4 = 20 bar, roughly, 1 full turn = 80 bar. 2 full turns = 160 bar. 160 bar = 2350. So anothet half turn would be 200 bar or roughly 2900psi. Am I mistaken somewhere?

It doesn't start at zero though. It starts probably around 2700 psi but it's going to be hard to know exactly on a regular Challanger without a reg gauge.

It's adjustable within a certain range but not to zero so you can't just turn it all the way down and start from there using that math.

I would air up, to 4500 psi, with the nut fully tightened, I would slowly release it till I get to 2.5 turns. Again if I’m mistaken, please correct me. I did ask bin and Pete a question via messenger yesterday, I just didn’t get a response to that question so I didn’t want to bother them more.

Ahhh, so my assumption that it starts at zero is where I could get the reg in trouble, I see. Pete said couple days back stock is 27-2800. Maybe I can degas and turn it clockwise to see how many turns. Ur sucks that it doesn’t have a gauge but I’d still rather have a reg than not have a ref.
 
I'm not sure how you're planning to measure the reg. It sounds like you can safely turn it CCW about 1/8th turn but that will be bumping up against the limit.

Anything besides this IMO greatly increases your margin for error. Assume it's set to 2800 to be safe and adjust accordingly.

"Close enough is close enough" (y)
Without knowing for sure what the start is, I really have no choice but to take their word for it. If I knew what the starting psi was, I’d adjust it close to what I stated. If you can get a hold of either? Thank you for your guidance
 
Is this what y'all are referring to when you talk about "turning"?

Challenger Pro 30 just like I have... so slightly different instructions vs a regular Challenger with the reg upgrade. But for you and Challenger Pro -- degas the gun via the regulator gauge (unscrew it slowly until air starts leaking, then wait a while). Then you unscrew the tank by hand. Once that's off you'll see a thingy in the middle. There is a fairly large hex head in the center of it. That's what you twist either CCW to increase pressure, 20 bar per 1/8th turn, or vice versa clockwise to reduce pressure.

I would have taken a photo today when I did this on mine. Went from 2900 psi to 2800 psi. I think I was overpowering my slugs a touch but they were one-holing at 75 yards after the adjustment. I like to leave the "power wheel" adjuster alone for the most part. It's very touchy. I prefer to just keep it at max for slugs and adjust it to a certain known setting if I want to use JSB pellets.

When you go to screw the tank back in, put a little silicone grease on the o-ring. Just a dab on the ring, it will get all up in there when you screw it in.

edit 20 bar not 200 per 1/8th turn!

I'm getting a .25 cal Pro from Sig Shooter next week. Based off what I'm reading, the gun will come at 185 bar. I've heard that the 41gr Zans shoot well at 160 bar. So that should be about a 1/4turn clockwise adjustment.

If you have a chronograph you can also leave the reg set higher and turn the power wheel down until you get the right speed. I think either way you'll get the same number of shots before it falls off the regulator. Then you can buy some heavier slugs and really take advantage of this platform without having to do reg adjustments going back and forth. Enjoy!

Things don’t seem to match up. It’s supposed to be 1/4 turn = 20 bar, I turned 2 full turns, 160 bar at best was still overpowering regulalator, shots from mid 800, to mid 900 and back down. I then went and turned hex all the way to stop after degassing, this time only 1.5 turns. What I found with help from someone is snipping off coils on the heavy spring. The light spring was way too light. The heavy spring, we felt was too heavy, hence snippping off coils. Now I’m able to shoot 91 grains in the mid 800’s more consistently ..no bell curve.
