Just a note for a comment above. Not everyone has a chrono so may not be aware of the issue. And if they shoot 24/30/40 yards might never know. I don’t think 50 FPS at that distance would be noticeable in terms of POI.

So Halop ammunition is actually being released.. Wow.. I wonder if it will live up to the hype. Do we know what weights it comes in? Mike

The FX marketing is strong :) LOL What I don't understand why this hasn't been fixed. I assume 1-3 shots is relatively normal for most regulated guns? Mike

I have the Challenger PRO LB. It's the 30" barrel version. Very powerful. Mike

Waiting for Ammo sales to start :) Mike

This listing has been renewed

Thanks for info.. I have mine set at 265-170 BAR and hammer spring turned in maybe 1/8 of the way and getting 990/1000 FPS on those. Waiting on my scope to get out and do some 50 / 100 yard accuracy. I have the newer Gen2 with the adjustable hammer. Mike

Thanks for the info. I read the whole linked thread. Was very informative.

Have you looked at the Challanget Pro?

I’ve rebuilt a reximex Daystar / Pretensis. Probably same valve as in yours. The valve may not be suited for such a low reg pressure. I’ve ported and run at 180 BAR and my shot string is flat as flat can be. Maybe plus / minus 2-3 FPS It could also be the reg. Have you tried increasing it to...

Im curious now that these have been out if there is a consensus on good target speed. Traditional thinking from what i have seen is that pellets should be fired 880-890-900 speed(ish) This makes sense as past Mach 0.8 you run into stability and drag issues and with a projectile that is drag...

Thanks for the reply guys. Also the gauge on regulator actually is not a regulator gauge but measures the pressure in the plenum, correct?

Curious.. Are the regulators in most guns sensitive to fill pressure.. Lets say REG is set to 2500PSI and was set when tank had 3000PSI in it. IF you now fill the tank to 4500PSI will the REG still be set to 2500PSI.. Not sure exactly how the REGs work IS it an offset or its an absolute...

Thanks

Thanks. These would be the ones you are recommending? Saber Tactical Universal Picatinny to Arca Short ST0024 And Strike Picatinny to ARCA, 1/4", 3/8", QD adaptor

Those are some great groups. Pellets flying as well those speeds.

Thanks for the response. I’m mounting a AEA challenger pro LB. It will be 11 pounds with scope once fully assembled / Mounted tripod. It has picanny on bottom by trigger and another one further down on air tube. Son probably sticking with picatinny as no way to run a different rail really.

Just got a 30 CAL Challanger PRO LB (Gen2) with the adjustable REG / Hammer. Curious if anyone has tuned these yet and what settings they are running. REG came in at 170 BAR and Hammer all the way out. I'm getting 990 with the AEA 50.5 Grain pellets currently. Also has anyone slugged one of...

Looks great. Any upgrades to the rifle itself or this just a chassis upgrade?

Just came across this and ordered one @. 290.00 shipped.. I have another cheaper one on my other rifle and like it.. Pretty good deal for the price.. https://www.discoveryopt.com/ED-PRS-GEN2-5-25X56SFIR-FFP-Z-Optics-Scope.html This is the one with Japanese ED Glass Figured I would share.
