I bought a standard power Red Wolf in .22 recently. After going through a bad barrel, it is now shooting well with the replacement barrel. It shoots the JSB 16 great on midpower at 900 fps. On HP, it shoots the JSB 18 at 940, and accuracy is good, not great. I think it is shooting a little fast, and would probably shoot the 18 well in the 880-900 range. It shoots well on MP at around 840. I haven't tried the Monster 25 yet, waiting for some now. I know the Red Wolf HP is currently receiving most focus, but if anyone has experience with the standard power rifle and the JSB 18, I would be interested in hearing your results, or, other recommendations for the HP setting. I expect I'll end up tuning it down a little.

I have the standard as you call it, FAC version here, mine is set exactly as you say with the 18.13g JSB at 880FPS for 75 shots, literally one hole, the accuraccy couldn't be better.
Had some 1" 5 shot groups with it in reasonably calm weather.
The 25g .22 JSB Monster redesigned gets me to 750FPS, way too slow I think.

I'm going to try the JSB 25g, Although the 18g is a bit fast, I think the 25g requires more power, and my best option will be to slow the 18 a little.

With the 18.1's and the traditional rifled barrel (which is factory on the lower powered US guns) the best results I have heard have been shooting them starting in the mid 800's and seeing how far out the groups stay tight. As you speed up the group will hold together farther and farther until you reach a speed where they are no longer stable, low 900's seems most common. Once you find the sweet spot and distance you are good to go within the limitations. It seems most are in the 880 to 920 range and good to between 70 and 110 yards.
I'm working the same issue with an HP on the 25.39s right now. We just got a programmer and can't wait to see where it takes us.

My standard FAC red wolf in 0.22 is set to shoot the 18gr jsb at 920fps on high and it is hole in hole accurate with several 6mm ctc 5 shot groups at 50m on calm days.
I tend to agree - 940fps seems a bit much.

The original barrel used a threaded air stripper at the muzzle, as you can see in the photo. At some point, Daystate realized that threading the muzzle upset the internal dimensions of the bore, and accuracy suffered. I'm sure many rifles with the stripper shoot fine, mine did not. The replacement barrel is not threaded and does not use a stripper. The short bushing fits at the muzzle to center and support the shroud. The longer bushing in the photos is the breech end bushing that fits just forward of the action. AOA sent me another one, as it can be attached near the muzzle also, but the shorter bushing gives better results in my rifle.

In my findings I'm seeing the 18gr very accurate at 880-930 in HP model with polygonal barrel. Not the case with the standard model with the tradition LW rifling. The LW rifling is more aggressive on the pellet and leaves the pellet with pronounced lands on the head and skirt, thus making it more acceptable to wind and destabilization at higher speeds. So the 18gr speed is best in the area of 850-890 depending on the individual barrel. The poly barrel barely deforms the pellet making it less acceptable to the elements and can handle the higher FPS. Ive tested the 18gr as high as 1000 fps and was stable to 75 yards, but see a few more fliers than usual, very good for small game woods walking. the 16gr Ive seen great results at 950 fps as well, please note these may vary from gun to gun. The 25gr monsters I have personally pushed to their limits at 1100 fps with eye popping accuracy, but this is also I feel is beyond the Wolf's comfort zone, excessive heat to the electronics and instability to the whole platform. I am sure there is a proper program for these speeds, I will continue to search for it in my tests. I will be at Daystate in a month, I will have questions and pad/paper.

what speeds ken are you finding the 177 call most accurate out of the redwolf? with both poly and lw barrels? I assume as well only the poly is available in the hp 177 as well?
