    I'm not sure if this topic belongs here or on the PCP page, but I'll ask here first.

    A couple years ago, I picked up a few tins of the RD 25.39 .22 pellets and shot them thru a Charlie Frear tuned standard Cricket.  The groups were practically hole in hole from 25 yds out to 60 yds.  But I could only muster about 775-790 fps out of the Cricket.  Personally, I think a PCP that can shoot these pellets over 900 fps would really give the shooter the ability to get .25 cal ballistics out of the .22. Long story short, I ended up selling the Cricket (regret!). 

    Since then, Taipan has the .22 Long and Brocock has the Sniper Magnum in .22.  Those units can push those pellets over 900fps.

    I'm curious if any folks here have any tuning advise on how to ramp up the fps of the other PCPs.  Any of you using other PCPs besides the Taipan Long and the Sniper Mag to get +900 fps?

    Thanks!

    My Redwolf HP pushes them like a laser at an average of 929fps, with an out-of-the tin 40 shot string SD of only 2 FPS.  It will consistently group +/- 1” at 100 yards – better than with any of the probably dozen or more slugs I have tried.  
     

    Good luck!

    My Pulsar HP is very accurate with the redesigns at around 940 FPS.

    I guess it's a bit of a different class of airgun but my Condor SS easily pushes them over 900 fps. They shoot  very well at that speed.

    They are the most accurate pellet I’ve tested so far in my Brocock Bantam Sniper HP…..LW polygonal barrel.  Without any adjustments on the hammer spring, it shoots them at 890fps.

    I buy a taipan veteran long in .22 with the intention to use those. 25 redesigned..but it did not shoot the redesigned well 100y + even at max power..maybe opening the gun n changing the regulator pressure it  might work but I'm no airgun Smith..so I sold it..I buy now a .25 cricket sheep so I could send it to Ernest to be converted to a high power .22 slug shoote..now I hope I could shoot those redesigned well..my 2 condor barrel loves them 18" n 24" and now that is regulated is simply awesome..

    I shot the RD's through my Red Wolf at an astounding  974 foot per second with total accuracy . I was talking to Matt Dubber about it and he was shocked that they worked so well . So much so he tried in his FX and put the speed up to 1000 fps and guess what … Bang on !  They grouped really really well at 100 yards  . He sent me a vid showing how good they were , I was  was surprised at the accuracy  . I want to try them even faster to see what they top at as it were . They are a great pellet to be honest , well in my gun they are .

    If I recall correctly, Claudio florez won extreme bench rest with the .22 redesigns and a modified bantam with the same logic you said above.

    The magnum version of the bantam sniper was made to replicate that gun and had the same lw barrel. It is one of the most accurate guns available on the market with those redesigns if we are to beleive championship results are indicators of a guns ability.

    Thanks for posting everybody!  My budget regrettably doesn't allow for a Red Wolf or Pulsar.  But the Brocock seems to be getting good reviews…time will tell….

    I'm not sure why this is the only pellet in my experience that semi acts like a slug as far as speed.  Maybe because it is shaped like a pellet/slug hybrid?  Not sure.

    I do know that out of my .22 Eddy R3 Long its a laser out to 100 yards (935 FPS). But past that, a funny thing happens depending on the temperature and weather. When its fairly sunny and under 65 degrees, its a laser at 95 to 100 yards. Then as soon as it goes past 100 yards out to my usual target distance of 110 yards, I can't hit the side of a barn. The pellet loses stability right past 100 yards.  When its hot out (85 degrees or so), this doesn't happen until just past 115 yards. 

    I'm kinda baffled by this, since the 20.2 grain NSA at 985 FPS stays stable until it hits the ground, no matter how far it is…  Perhaps its because the Eddy has a 1:16 twist rate, and as the RD Monster slows the spin to speed ratio becomes too high and the pellets becomes unstable…?  That's my theory but who knows for sure… ;)

    I think that its all down to Twist rate if you ask me. I agree with your findings to a point, mine can shoot really well to 125 yards , after that it all goes wrong . 125 is more than I need . I have shot many slugs through my Red Wolf and as you say they stay true all the way out. It seems that pellets under a certain speed go all over the shop . I might try that out again when we get some good weather over here in the UK . Would be good . 👍

    It because the gently slopping pellet skirt can only get the drag it needs to stabilize at extreme speeds.  Once it does not have the drag to support it's flight it goes haywire.

    Its been about a year since I've shot them out of my .22 Taipan Veteran Long. They become unstabilized someway between 10m and 120 yards. At the time I had my first steel target at 120 yards, so I haven't been able to determine where they fall apart.

    I'm heading to the gun range tomorrow, primarily to shoot my powder burners, but will bring my Taipan Veteran as well as some RD monsters and 18 grain JSB exacts and FX slugs to do some testing at 100 yards. 

    I just purchased a Talon Tunes power spring for my Taipan Veteran, which is supposed to increase speeds by 80-120 fps. I'll play around with that when I get it and see if that helps with the RD monsters.

    The RD monsters shoot amazing at 10m, but I want them to shoot good to at least 100 yards. I really like the idea of a hard shooting, fasting shooting, high BC .22, and if I can get it to work, I think the RD monsters and the Taipan Veteran Long could potentially be a great pair. I'm hoping to shoot the EBR match in Phoenix this year, hopefully I can make this combo work.

    Wasn't able to make it to the range, my dog wasn't feeling the greatest this AM so I decided to stay around the house with him.

    However I was able to put up a target at 160 yards, and same results – RD monsters were all over the place. 

    Once I get that power spring I'll retest. I also plan on going to the shooting range on Monday, testing various pellets and some FX slugs at 100 yards.

    On the chrono, the fastest I can get the RD monsters without the power spring is ~860 fps. I'm hoping the power spring puts me around 930+ fps.
