    Hey guys!

    I was having a time even finding the power plenum kit to purchase anywhere right away.  But Precision Airguns and Supplies in Michigan have them ready to roll out the door for $175.

    Mine is coming UPS AS WE SPEAK!

    No sir, it's difficult.  Shoot man,  i reasoned if I spent 2100 on my Impact,  (+721 for Hercules,  679 for Sumatra…) I may as well go on and drop a measly 259 for the young hen air compressor! That thing is great! Our sport changes so drastically once you can stop having to factor limited air into the equation.  Promise! I can't believe anyone is without one these days.  They used to be 3 grand,  but now we finally can afford it.  I fill my guns over and over,  and my 88 c.f. tank too about 4800 psi when I'm traveling. Paintball shop used to max at like 3900. That crap sucked! Lol 😛

    Yeah…. Lol

    Screw that.  I'm just gonna go with the power plenum  kit and shooting healthy 70+ grain .308 slugs. Melissa at FX Usa talked to her manager,  and even though I received my rifle on October 19th, she talked to her manager,  and they are gonna install my kit for the 100 dollar discounted rate.  The cutoff was October 31st, I had missed it by less than 2 weeks.  3 month estimated wait time,  like any new fx thing,  but I'm so grateful they're cool, and are blessing me. 

    I can't wait to get it back all beefed up!😁😀😆😅😄😃

    Hey brother!

    Let me bring to mind the Hercules .357. I know outs a beast,  but with its 1,000 c.f. of air at 250 bar,  you can shoot 2 full 9 round mags before the velocity drops.  Accuracy is 3/4" at 50 yds with the heavy 97 grain pellets from Ricmor , (If I'm accurate) a seller on eBay.  I have shot a best of .66 with those pellets.  Or…. the much more nimble .35 Hercules bully.  Can't beat the price either.  You'll have to change out the not – well – thought – Out scope rail system on the bully.  A forward – extending picatinny works great if it's rigid.  They're both accurate and built like tanks.  Also they'll shoot 75 to 95 grain epp/ug and the .357 Nielsons very well.  

    Just my .02

    Hey Ghulam;

    I just got measurements on digi calipers on mine. 

    It's 44 on the eyepiece,  and  58 on the objective by outside diameters. 

    41 and 55 respectively,  for inside diameters,  but those outside measurements are what will give you reference if you measure the ID of what you're buying,  if that makes sense.

    Many blessings for you and yours, sir!

    Bro,  I've had mine since ive owned my impact, about three months. In that time, she's slid down once on hardwood , and has fallen out of the truck door one time. Never moved. Once you get used to the Fine crosshairs, It's a Wonderful tool. First focal plane is a new feature to me, and I'll never look back. Very consistent, and I would recommend it to anybody for 250 bucks. I take plink target shots at night; draws light in great with 50mm objective. Illuminated reticle works flawlessly.

    Just chiming in, 

    My impact seems like it has gained a little power as it breaks in, I may be tripping, idk.

    I love it, man.  Only truly consistent pcp I've owned besides my .35 Hercules, and more so. I can pick it up at any time and knock a bull out at 50 yards without fail.  

    I have mine tuned now where I have the right harmonics and 1/2" or so groups at 50 yards with 29.5 grain flat based Nielson slugs on max hammer, running about 930 fps. Of course that's the slug liner,  but…. I can also turn the hammer wheel down to 3, and shoot 1/2" groups with JSB 27 kings at 920 fps, requiring only a few clicks down and a couple clicks right on my scope. I can turn it right back to max,  and slugs are good again.  I shot the kings on max,  and they're exactly 1,000 fps with accuracy that isn't that bad; inside 3/4 inch at 50. This is all with the valve knob only showing a tad over 3 lines. My reg is on about 158-160, though.

    I love the possibilities with this platform. My Sumatra and Hercules feel like butt crack after I've gotten used to this gun,  ha ha! Its got my vote.  Yes,  it was a tad expensive,  but when your barrel machine costs 10s of millions, hey…. Ya gotta recover somehow! :-/

    Ahhhrghh!!!

    Lol, I'm used to impact forums! 

    I was just naturally thinking that's what you had! Ha ha! Ooh well,  maybe some of the same characteristics carry over.  It'd be very cool to find out.

    Ha ha ha!!!

    Thanks, brother! Hey, I don't even have proof yet, sir.  Lol

    I gotta get a scope cam.  Mine will not group dish base less than 1.25 or so at 50 yards.  Flat base 29.5, .249 is what she likes.  I watched a couple videos (Matt Dubber and one other guy) where there emphasis was a resounding "harmonics, harmonics…" we have to make those painstaking tiny adjustments of that valve bumper starting down from 950 fps or so.  It's always 930-940, so it's a fairly tight range where it works right.  

    I would try those slugs I mentioned if you haven not in .25 caliber, dude.  That 950 fps capability, then work down….. seems mandatory.

    One guy said sight in at 25 yards in 3 shot groups (saves lead) till you get 3 thru a ragged hole,  then take it out to 100. Forget 50 yards.  They hold good at 25; they'll keep holding on out! Don't expect the one hole at 60 like pellets, but,  they will hold less than 1.5 inches almost indefinitely,  and they just seem to always hit long shots.  And they carry SO much more energy at long range. 

    Ha ha…..i ordered 3 more boxes of 300 today!

    Good luck and my prayers, sir!

    Have a merry Christmas!

     that's great, Ranchibi!

    I'm thinking I got mine from airgun optics as well.  I caught it early at $249 I believe it was.  I take 300 yard shots often with the. 25 cal impact and Nielsen slugs

    I have the disco 4-20×50 FFP also on my .25 caliber impact x. I'm shooting 29.5 grain Nielsen slugs at 940 fps, and I have to say,  love the FFP!!!

    Same holdover at any power,  that's something to be happy about! I have a Mueller 8-32×44, thought it was the best sub 300 dollar, but this one has it beat in features.  Mueller has a little clearer glass, but it ends there! 2nd focal,  less light gathering,  edge blur over 16x, etc.

    Nice review, sir!!!!

    Hello!!

    I have the 700mm .25 slug liner. My bumper is showing 4 marks,  but has had fine tune backing down to get good groups. Regulator is on 160 bar by its gauge. 

    I first ordered 38.5 hp, 36 dimple,  and I think 33.5 hp. Still having stock gun,  stock bumper,  and all,  I can barely get the 38.5 to 800 fps. Then I ordered 29.5s, and they max at 940fps. I went all the way out with bumper knob,  and began backing it down in very small increments,  3 shots each time at 50yds.

    I get about .5" at 50 yards at that perfect setting,  but it's over 50 yards where they shine,  holding that speed.  I regularly hit drink cans at 300 now. 

    Hope this helps.

    I'm gonna try the 26.5 dish base next.  Got a box now, and in betting I can drive them 1000 fps. I will measure my valve bumper -to- receiver with calipers before I move it lol.

    Hi guys!!

    I've used the little nylon washers in the specialty drawers from Lowe's a lot for hpa stuff,  

    Like 5k worthy compression hpa seals in my Young Hen air compressor,  (🤣) 

    And I basically rebuilt all the funky fittings in the valve on my outta date 60 minute scba tank I fill with it using those things. 

    Not sure if there's any correct sizes and thicknesses in them for this mod.  I didn't see out anyone gave good dimensions for the bumper mod Delrin/Nylon piece yet…..

    As always,  a pleasure visiting, dudes.

    Yes,  I understand fully the principles of valve lock and how its encountered.  I'm saying that velocity dropped when going from 150 bar down to 135, and gained when the gauge read 156. That's why I was wondering why I seemed so weak,  because I know it's not into valve lock at 150 bar.  

    If I seem to still be missing  something,  I do wanna listen to ideas.  

    Thanks,  guys!

    Hi again gents!

    I did try the recommendations y'all gave me of dropping my reg from 150 to 1:35 ish. Velocity only dropped more from 835 2 around 8:10.

    Reminder, this being in 25 caliber with regular jsb King 27 grain. I finally decided my gauge must be reading very high, after seeing the video about the adjustment screw being flushed at its limits. Mine was steel recessed. I adjusted it slightly where I'm reading 1:56 or so. Then I threaded the valve bumper outward to the fourth line. Was too dark to read the chronograph, but there was a noticeable increase in velocity just by sense. I was wondering if I just got a really weak tune, or build for that matter. Thank you all for your help

    Hey guys! 

    Sorry,  I know the thread is old.  

    Was just wondering what gives;

    I have a relatively New Impact X in 25 caliber, 700 millimeter Barrel. It came from the factory set on 150 bar, there is no slack in the hammer spring side piece to adjust out, and on max I'm only getting 835 feet per second with the regular jsb King 2 6 grain. I was sure hoping it would be more like 900.

    Now mind you, it shoots a ragged hole with three different pellets,  the jsb, the jsb heavy, and poly. mags.

    B.Ragu,

    I got the bully at midway for $544 on clearance in .25 caliber. I also swapped out the rail for the bull master.  Cost me 15 dollars and 5 shipping from Hatsan USA.  Also dialed down about  9 turns on spring, I might have 5 threads left to reduce off I had to.  It's averaging 900 FPS with standard JSBs for about  45 ft/lbs. I'm busting ragged home groups at 35 yards or so.  

    I also ordered a picatinny mount picatinny extension rail from Amazon that's a tad shorter than the bull master rail,  but looks like it would be stronger still! It attaches to the actual receiver front with 2 large bolts and nuts type mount. The front screw almost sits too far front, but it will work.  It would need about 1/4" ground off the plastic outer part of that first rail mount on the stock to fit, but it's a beast. If bull master rail fails,  is next,  but…. so far so good!
