    Those help the harmonics ergo the accuracy. can you shoot without them accurate? for sure you can! but with them you can squeeze a bit more of accuracy, especially in larger cals (more vibration).

    In .30 cal you'll get much better performance with the larger eccentric plenum produced in Poland (both are my design). You won't gain anything by combining the eccentric plenum with the external unless you move up to .35 cal. The older rubber ball valve control works better than the spring in the FX plenum kit also.

    Both what are your design?

    The eccentric plenums from Poland and FX. The design was copied from a CAD drawing I posted here in April of last year.

    Dang copy cats! you should sue them!  ☝

    My favorite is the 65.5gn ;)

    i now him wel( in Poland) 1: he doesn't steel ideas from other people2: he already had such a plenum on his own gun around February. 3 : the new valvehousing will never be able to produce the power of the previous versions.

    With the prebious versions, I’ve seen loads of videos shooting 60 grainers above 1000fps. Haven’t seen it happen with the new version. The new POWER plenum is good, but all the rest that comes with it isnt! Back to the drawing board. 

    JMP EXPERIENCE. I own 2 impacts. One with the FULL Polish kit, and since last week, a from factory build Power plenum impact mkII .30/700.  TBH : thats not an upgrade!

    Hi Rudder, regarding PolishPlenum, you are probably right, still some are claiming copy. ;)

    Do not forget the impact is a multicaliber airgun and FX must make an upgrade to fit all, I shoot heavy stuff for a loong time with the impact (in airgun time of course, tech changes fast ajjaja) and if you power up too much, then 18gn and below will not work to good and using the valveknob is the only way to put the speed down (loosing some hammer spring tuning). The VH now is much more easy to drill! /the ex VS) jaja IMO with the right knowledge, you can change and mod a few things and power up all. But I agree with you, as is, the max I reached is 970fps (with transfer ports lager) with the 25.4gn monsters .22 @ about 135-140 bar, over that no gain. (I have not tested much tho). Will see how FX will stay multicaliber with the .35

    @edosan Will we see the Silver Surfer there? I hope so!

    Haha will see, still need to test a few more airguns but for sure is a candidate to be there.

    @jiikuu I might be wrong, been a while since I shoot .25 55gn, maybe is max out @ 160b (at 1000 fps) … I might go soon to Wild Goat hunting, I will test good with the .25 (.22 is the one I use the most and test the most, then .30). as soon as I test it, I will publish it with some pics. (been lazy testing lately … summer time here and too hot).

    Anyway the point is that going up in cal is more efficient than stay in the same cal and going up in weight (when you are over the limit) right now in .22 cal I like 30gn in .25 cal I like 44gn and in .30 I like 60gn (or so bit more bit less) if I can shoot all those @ 1.000 fps then I am good and happy! (and I do).

    Normal 217 sized barrel difference to 224barrel bore area is less than 10% so you could reach 100FPE even with 217 easily just not really practical since there is no barrels with fast enough twist to stabilize bullets heavy enough to hit that goal without going supersonic so unless you want to upgrade it to firearm barrel you are kinda limited to 70-80FPE of practical usable energy and like on Edosans gun should run with really long barrel to have that with reasonably low pressures. 

    Agreed, IME about 80 fpe is the max for .22, can you go higher?, for sure but you will lost a lot of air, is much more efficient to go higher cal with that same setup, just changing calibers (barrel and pellet probe on an impact) I get about 120 fpe on .25 (55gn slug) and 150 fpe on .30 with a 66gn slug (and if I add 160bar on the reg I reach 160fpe), that shows that is way more efficient to change calibers, only difference is the transfer port holes. Optimal for .22 is about 50 to 70 fpe (on an impact of course, only test I have done)

    For those of you with PCPs in the .216 – .218 range, where are you maxing out on energy? It would be helpful to know the:

    1. Rifle & barrel length
    2. Ammo used for the calculation (incl. diameter)
    3. FPE / FPS
    4. Reg pressure (or indicate unregulated)
    5. Mods (if any)

    Thanks 😎

    Little guy here! ;)

    1. Rifle & barrel length: FX Impact Mk2 Aka Silver Surfer 700mm
    2. Ammo used for the calculation (incl. diameter): .217 36gn Slug
    3. FPE / FPS: 80fpe (1000+ fps)
    4. Reg pressure (or indicate unregulated): about 140b
    5. Mods (if any): Lots! jaja (there is a post about it)

    edosan, what speed are you flinging the 65.5 at?  Someone said I need to be in the 950s, I'm no where close to that.

    You should be good at lower velocities. My MKII was accurate with them from 850-920. FWIW, my R5 shoots them well as low as 770-825FPS

    @monstermaxx sorry for the delay (I usually stay away from cry babies .. jaja not you) , yeah 850 and up should be fine. I can shoot those over 1.000 fps but best accuracy is in 900ish range IME. If you ask me if the slug fly ok over 800fps, then choose the one is more accurate in the barrel/liner u use.

    The shroud DOES help a lot on muting + the moderator. If you see FX moderator is just an empty tube. inside the shroud there is a sort of diffuser that send the air to the shroud and the moderator. Easy test to check that, remove the shroud and attach a moderator 1/2-20 thread direct to the barrel (you can) then you will hear the sound.

    if you talk about a donno 10 shot mag, not much benefit.

    But when you talk about a 19-28 shot mag, big difference. Much more easy to load. Once you get use to a 28 shot mag, is kind of hard to go back.

    that is called fire lapping , I have done it, but did not get the results I get polishing the traditional way. 

    I have read good experiences, but that was not my case. (you can find fire lapping kits on ebay)

    looking good!  see!? I remember you were reluctant to get one a while ago! jaja 

    How about the unborn child between the RW and the IMPACT? can wait to see that one! ;)

    I didn’t word it well I guess, but I’m admitting that my impact is equal to or better than my red wolf!, and I was saying basically nothing could beat Daystate’s electric firing cycle, nothing against edosan or any other members.   I Just learned a important point know what your talking about before you open your mouth! I’m taking a break….

    jaja sorry just getting back from a hunting recon trip (Red Deer) no luck but the place is awesome. No worries, I get what you mean. No sorrys accepted! jaja 

    For me and so far (I have not test all), the best 2 airguns I have tested  are the FX Impact and the RedWolf HP, no doubt about it, both have some good and some bad, and that is why I am so excited about the Delta. That one have the potential of been a HELL of a gun! … sadly in the US …. FX vs DAYSTATE is getting too political. :( 

    @ronin001 like that too!
