1000 fps for 30+ shots with the 18 JSB is solid performance out of that package.
JTS JTS AIRACUDA STANDARD .22 Owners!

I was thinking about adding one of those drop in style regulators but after reading I think tuning might get desired results.
I ordered a cheap chronograph but currently the jts 18 grains shoot the best out of 7 pellets I've tried. However my issue is it shoots a 1.5 maybe more line up then down . My left right variation is within a dime and from what I am learning this is due to the "shot curve"
I guess ill start with 2 turns out from seated. Then go from there to see if it tightens out at 3 turns.
Is everyone tuning on power level 5? I've seen some on level 4... I'm kind of hoping I can shoot 14 grains on level 3. 18 on 4 and 20 grain slugs on 5 and just find the most accurate lead for each.
Any tips would be appreciated.
And thanks for the add. First pcp. First post. Sorry it's so long. I've been lingering a bit on the forums and just now finally joined

@DoktorPotterR - I shoot cheap Crosman Premier Hollow Points 14.3 grains out of mine on power setting 3. I left my hammer spring where it was from the factory (mine wall all out/flush with the back of the receiver. When I did the shot curve last year for that combination it gave me an average muzzle velocity of 806.4 fps for 20.6 fpe. I keep it at that setting for plinking and pesting. The sweet spot of my curve was 2600 psi down to 2000 psi, gave me 40 shots with an standard deviation of 4.7 fps and and extreme spread of 19 fps. If I'm just plinking I fill it up to 3000 psi and shoot it for 100 shots.

Got mine a few weeks ago. 22 caliber. Very accurate. The scope in the picture went back. Trying a Hawkes 3-9 now. One dime at 45 yards with Dead Center 18.1. Not as good with 14.3 CPHP. May order an Arken. Adds another 1/2 pound. It came with a horrible stock color but I could see nice figure in the Beechwood stock. Simple refinish. Before and after.

I like that stock color on the refinish! Mine does not have near as much grain to it, and it still has tooling marks on the bottom of the stock. Good job!

My posted shot strings, 3 clips for 30 is with the hammer turned IN 3 turns from flush or stock out of box. I easily confuse myself. Anyway the cheap Cadwell lets you save your string on phone, me old 6S phone using the round mic jack. I lost 200 psi per clip but the FPS/FPE hangs in for a hunting curve. Using lighter pellets like Chris, don't see spending bucks on a regulator, for way higher shot count. Waiting on your post...

Thanks.so what was your simple refinish? how did you do it? looks great!
Strip the muddy factory spray stain off with a paint and varnish remover. Use Lacquer Thinner to clean off the residue. After the wood is thoroughly dry, use synthetic wool to lower the raised grain. Caution: Do not over do it. Beechwood is very hard and easy to close the grain so it will not accept stain. Stain, then a couple coats of spray lacquer. After the finish is dry, lightly rub it out with oooo steel wool.

Yes. My hammer spring came from AOA and was turned all the way out. I use a hand pump, so I want to get the best cycle without taking the psi to low. At 3k and on setting #3, it starts out at 846 fps using 14.3 grain CPHP’s. At shot 58 and 2.2k psi, it’s getting 851 fps. Shot #25-52 approximately, is its premium portion of the cycle. 859fps-860fps, topping out at 866fps. Then with 2.2 k psi left, at simple 75 pumps on the Hill pump and it’s back to 3k. Accuracy seems reasonably good. Just upgraded the scope to a Nikon 3-9AO, EFR from a Hawke 3-9AO and should improve the accuracy even a bit more. Will keep everyone updated.

I have the Max in .177, and I was gonna change the hammer spring tension, but I couldn't turn the screw on the back at all. Is it possible that there's blue locktite on the threads?

I did. It's beyond snug. Lol. I'll get a heat gun.Take action out of stock ... Set screw at rear is snugged up

If your using the Caldwell, it's finicky on light. Wind blowing leaves will error 3 if tree overhead. Rock solid in the shade or inside using homemade uv light string. My brother killed my old F1, same light issues.

There's a set screw on the left side I believe that locks the adjuster screw from turning. You have to loosen it first before the adjusting screen will turn

Haven't been able to get to my shot string to measure fps. Noticed my pressure appears to be dropping when the rifle sits now. Was at 3000 then after 7 days was at 2k. Just topped off and worked action. Seeing if it is just when the hammer isn't cocked.

I have never gone over one full day of non-use on mine. I have never let mine sit that long. Keep us posted.

First few months I had it never lost any pressure. Id shoot it every few days. Sometimes only once a week. It's been a few hours and has dropped. I've only put about 2k shots through it. Probably needs seals piled I'm guessing. It's slow . But enough to see it move from the 3k jash to below the 3k hash in a few hours. Will check later.
