Ghost Initial tuning test .25cal GHost

[Corvid_Hunter]

I went out the other day to try a few groups at different velocities. It was typically windy, variably about 10-13mph between 10 and 12 o'clock. 30 yard 5 shot groups with unsorted ammo out of the mag. The targets that have Min written and 2 groups would have had the first group POA on the center and the second on the top of the target. All other groups were held on center of target. Atlas bipod and a rear bag rest. I will be degassing my rifle and starting around 130 bar and working up to 150 bar when time permits. Please excuse my chicken scratch writing.

Are you running a 23 inch barrel or the 28 inch?

Hmm looks like a couple decent reg/wheel combos there for accuracy! but 30Y isn't much....I am going to do this soon if I can ever put my S510 down! Did you de-gas completely to drop the regulator? I have heard from a few guys on HAM to lower it very low but not empty and then lower reg down well past your target, then repressurize and go up to desired bar. I hope to go with 150 bar, (same as S510, keeps it simple) get more shots, tame it a bit and above all boost accuracy. I have to still shoot/regroup mine off my new caldwell rest but I'm jealous of the Atlas bipod! Any pic of it all set up?

I'll take a pic of it for you the next time I go out. I degassed it completely before but will go down to 100 bar or so if that's considered okay. I'm guessing it likes to be shot around 930-940fps, so probably about 150 bar.

Finally made it out again. Ended up setting the reg around 147-149bar. One thing I notice with the higher velocity is a tendency for the POI to be on the right hand side of where I'm aiming. Could this be from excessive spin on pellet at the higher velocities? I got my best group at just under 900fps. I'll have to get out and try the speed up and down from there a little bit to see if it changes anything. I did notice the shot cycle to be much smoother at that fps. As I have the factory hammer spring kit I might try going one spring lighter and dropping the reg pressure to see if I can still get the desired velocity.

50 yards, single load with pellets sorted by head size. CARM loader in case anyone is interested.

Best group shot. I'm guessing the reason the 5th pellet didn't go into the same hole was because of me.



I don't see a lot of velocity change with this hammer spring/reg set up so I'm guessing the reg pressure is too low for the hammer spring? Has anyone found this rifle to be hold sensitive? I'm going to have to see if I can lighten up the trigger a little to see if that helps my groups.

Nice pics! My .22 has its good days and it's ho-hum days. 2 weeks ago shot my TX, Ghost, and S510 at 50 Yards. 10 shots, all off the same rest, one after the other. Ghost lost and it's by FAR the most coin, and gets shot the least. Cleaned barrel and its tight again! Seems like you don't have enough time shoot yours, I don't either?! The carm mags interest me! After shipping were they still cheaper vs the BRK mags? I emailed Maple Mags about one for a Ghost but they only make the older style BRK versions currently.

Dan have you ever tuned your ghost? If you’re still shooting @165 bar you are not in a good tune. For 25.4 turn pressure down to 140 and adjust hammer to get around 950 and go a bit above and see how it shoots. Mine shoots 1/2” groups fairly easily @50yds with 3 different calibers pellets and slugs

The single shot loader is $28.31 USD and the mags are $33.76 USD plus shipping. So far I've had his single shot loaders for my Impact, Crown and Ghost. Been happy with all of them. I do have one of his mags for my Crown but don't use mags in it that often. It seems to work well as I remember.

My .22 Ghost Carbine has been solid, definitely more accurate at 50 yards than I can hold… Mine came with the regulator set at 100 BAR, PW10 sending JSB Exact Jumbo 18.13s in the 890-900 fps range. I set the PW to minimum and send CPHPs accurately out to 50 yards… The Atomic and Pathfinder XR in the safe keep her on point. While the Ghost is the BRK flagship model, in my heart the Atomic still practically rules…

If more guys were wise enough to understand what they really needed instead of what they wanted fewer guys would buy the wrong guns. Your atomic suits you most needed purpose better than anything else!

Yes you are correct still @ 165 Bar. I dialed PW down to 10 (from 15) to get my 975FPS and accuracy back. Will be dropping reg soon is the plan!
Corvid_Hunter did you get the mags right from Carm Website then?

I’ve ordered numerous times from carm…If you have any questions just email them and within a day you get your answer….Never an issue at all and usually get them pretty fast.
