Thanks, will do. Since I hand pump and dont let it go below 200 bar, I look at the higher reg/plenum pressure as reducing the amount if air needed to achieve a specific velocity.

Ok was thinking True, I didn’t interpret his comment that way, but more along the lines that higher regulator pressure wastes air.

How does a higher regulator pressure contribute to wasted air when shooting? Isnt it all about adjusting the hammerspring so that the valve only stays open enough to get the velocity you are looking for?

Should have added .22 regulated at 195 barg from AoA, I haven’t adjusted anything…it loves JSB Exact Jumbos.

Its so accurate I was tempted to put a bipod on it but couldn’t get myself to “damage” the wood. If only it had a matching walnut cheek riser…

Thank you Miles, I enjoy the science of this as much as the actual shooting.

Ok, that was more difficult than I thought it would be...had to do that prone from one bedroom down the hall to the other bedroom.....did my pushups for the day + some.....the low lighting and tight eye box on the Element Helix made it even more difficult...but unfortunately the rifle-scope are...

Did a quick session in prep for MRD and Beast tunes. ~145 bar reg, MP spring, PW6 177 MRD ~ 930 ft/s ave; 25.8 ftlb; had to take Reg press up to get Beast to ~930 ft/s; settled out at ~160 bar and PW 10 ~31 ftlb. I can move the patio table to create a 50 yard range…hopefully the weather here...

Ok, so the 15.89-920 that is ~30 ft-lbf....So for that particular set up you dial back the PW to be sub 20 ft-lbf ~ 740 ft/s, then to shoot 100 yard, PW back up (MAX?) to get the 920 ft/s .... got it. When shooting FT sub 20 ft-lbf...how do you keep it sub 20 with each shot or two velocity...

Hello Fady, I am a relatively new owner of a Ghost and trying to understand how best to set ut up. Is your Ghost’s pressure regulator the same as the”production” model? What pressure do you have it set for? Or Is that a “secret sauce” question ? Thanks tc

The slugs slower because u were max PW? I am thinking there is a correlation between twist rate and optimal velocity-stability -accuracy for pellet or slug geometry? Still no replies from BRK, Daystate and Huma on any of my questions regarding design bases…

Hello Cole, what was the ft/s you were using to get this level of accuracy?

Will do…as soon as pellets arrive…really bad inventory control on my part!

Revere .22 "Bottle" 250 barg, Reg *190 barg. FX V2 Chrono on barrel right before 0db Moderator, JSB E Jumbo 15.89 gr unsorted. Definitely a louder "snap" when pulling the trigger, and the trigger is nicer (not adjusted vs the Ghost which I still haven't adjusted) and the shot is louder too...

Pulled out my .22 Revere..its such a beautiful rifle…but since the Ghost arrived I haven’t shot it…the Regulator (as is, unadjusted from AoA) is set at 190 Barg. Will try to Chronograph it today

That was my observation today that the .177 JSB Exacts and Beasts were tighter than the MRDs…at first I kept the MRDs ~800 ft/sec to be sub 20 ft-lb, but then started upping their velocity to see if they tightened up…maybe a little but still bigger groups than the other two (I need to get some...

I have been finding that the diabolos (JSBs and H&N BM) out of my .117&.22 HP barrels are 40-45 yrd most accurate at ~860 ft/sec

I was concerned about that too..I have the .177 and .22 barrels...and I use Super Lube on them in an effort to help preserve the alignment o-ring and reduce the friction/effort to remove/insert the barrels.

look down the barrel and make sure the screw is perfectly perpendicular before trying to thread it in...once the bottom threads of the grub screw are galled they make it super easy to start to cross thread....hope this helps

If you take the shroud off to clean/polish the barrel be dumb careful lining up the grub screws when you put them back, mine were so tight I thought my hex key was going to twist or strip...they put mine in so tight that they started to strip-gall the threads..so putting them back in was a 10...
