No one can answer that. You need to shoot a full string over the chronograph to see how it is performing now. The regulator is only a part of the tune.

What works for someone doesn't mean it's gonna work for you. Air guns are, it's sensitive to pretty much about everything.
You and I could have the same gun, have the exact same settings, and still get different results.
Your air temperature, your atmospheric pressure, the humidity, the altitude. It's all going to affect how your gun differently where you are versus where somebody else is.

I will only suggest you read up on tuning your gun and start somewhere that is proven, but that's not all you do. You need to have a chronograph and shoot groups to see where the gun WANTS to be. Its a process and it depends on what your standards are.

As a starting point, the reg in your new Ghost is probably going to need to be in the 100-110 range for a typical 18-19fpe in .177 field target situation. I've got one set up exactly the same, sitting on my bench in my gunroom right now.
Reg in the 100-110 window, MIN on power wheel is 890fps, and MAX on power wheel is 920fps. This is with .177/10.34grain pellets.

Just reread how many shots ....it's gonna be a heck of a lot, even with a 300cc bottle.
I skimmed my review and looks like you should see at least 130-140 shots per fill, assuming a 17inch barrel with a reg opressure of 100-110bar, with fps around 890-900 with the .177/10.34s.

I have a larger tank and the BRK website says 100 shots per fill in .177. I've never counted.

The fact that he is using jsbs seems like a hint but you should test both. I have found which pellet is the most important factor and I've never been able to get a gun to like a pellet by changing the tune. I'd get the gun in the fpe range you need per regulation (possibly 20 fpe limit) and then test suitable weight pellets from several manufacturers, pick one, then refine the tune to see if you can improve accuracy a little. You probably want pellets about 10 grains in weight. Jsb 10.34, H&N Baracuda Match, and possibly FTs too. Possibly others. At least some of the accuracy testing should be at 50 yards.

I can help you with this one, we have a thread going called ”ghost collaborative data request “
for Hft I recommend using jsb 13.4’s flying at around 810-815 FPS. So you will need a chronograph to check your settings.
Set the reg at or near 110/115 bar. You can increase reg under pressure but to decrease the pressure you need to degas. Brocock often ships their guns with the reg pressure set higher than necessary.
You should have received your ghost carbine with the white hammer spring installed. If all goes well you will be at or near minimum to 3 ? If my memory serves me well, on the power wheel.

I’m trying to create a cheat sheet for the FAC Ghosts when wanting to change calibers or barrel length and or pellets efficiently. I have ALL barrel(s) lengths and calibers, including a .20 available to me. I want to hear from folks who have found the perfect combination of: Regulator pressure...

cavedweller keith 1 here got my ghost carbinr 177 yesterday aoa test sheet stated number of shots were 10. minimum velocity 886 and 18.13 ft/lbs. maximum velocity 895 and 18.50 ft/lbs using 10.34 pellets. the other 8 shots range from 892 to 893 velocity and 18.37 to 18.41 ft/lbs. Im sad they didn't give the numbers from the power wheel for these shots? Like you stated i should shoot from minimum to 3 on the power wheel is this right? Plus AOA set my reg at 110. This is a great little gun my wife would ilke to clam it from my i say RIGHT".T HANKS FOR ALL YOUR HELP KEITH 1I can help you with this one, we have a thread going called ”ghost collaborative data request “
