Q:

Chronod my gun with the 25.4grain Monsters

I have my condor set on about 4 or so because anything higher was driving the 18 grain JSBs supersonic, and even this setting was borderline. Dont need that supersonic crack drawing attention around the house. Keeping that same setting I put the 25.4 grain JSBs across the chrono and got 968 fps and 52.8 ft pounds. I knew this gun was powerful but this is more than I expected at 4 on the power wheel. I am wondering what this can do wide open. One of these days I am going to find out.

Does anyone have the bc of the 25.4 pellet? I put the chrono out at 29 and bot 876 fps. chairgun calcd a BC of .035 which is different than the .044 that I have read. ( given the power of this I put a 1/4 square of steel plate infront of the device just in case). I am going to try to get a logner shot out there – maybe 50 yards or so and try the calc in charigun again. I figure the longer the range the better

Just for fun I built my own shroud out of black plastic pipe, metal closet clothes pole, some light guage sheet steel, epoxy and a bit of magic eraser and a tiny bit of packing tape (to act a s shim and minimize steel / aluminum contact. ) the damm thing works. No way is this thing machinest quality, its uses plastic. for christ sake. So long as I keep the pellet subsonic what I hear is the hammer strike and the pellet hitting the target. Other than the tools I already own I needed a 1 1/8 hole saw and a cut off blade for my dremel. and a new sharpie (my old one had dried out). You can actuallly do without the hole saw, but it speeds things up. The subsonic thing is critical. When I finished the shroud I was not impressed. Still heard a crack, figure iit was design or workmanship problem. it was the pellet going supersonic. Just had to turn it down to 4.

oh gotcha im thinkingg ill just stick with the 21 grain kodiacs then iv been looking for a good heaver pellet but nothing so im content for now. im happy with being able to kill crows at 120 yard on comand lol . thank u for u help

This rifle is destined to be turned into an archer, so no reg is its future, I didnt do anything to this, no mods, but got it used. No telling what happened before hand.. My impression is that 25.4s dont group that well in my condor or in my talon, but I cant rule them out. A more expereinced shooter might have a set up that works with them.

what kinda mods do u have to shoot these 25 grain monsters . and how the accrecey. and how far have u shot the to find good groups?

Air Density and humidity don’t affect a reg?

Put a etac-reg on it and be done. I’m sure Jim can tell u which reg you need to get the fps you want. I run a 2000 psi reg and shoot .25 JSB’s at 950 fps in my condor.

Wow – your gun on 4 is like mine on 12.

At a power level of 10 I see Kodiaks about 980. I at 450 ft elevation which slows things down a little for PCPs.

My chrony shows a 50fps drop when I shoot on the humid Fens compared to my back garden.
Air density/moisture content seems to make a BIG difference on my rig.

My elevation is about the same as yours, maybe a little lower, 375 ft ? I dont know exactly. Low air density is not a factor.

Be careful what you wish for. This gun exhausts the tank pretty quickly. Probably 15 shots and the POI starts dropping. By 20 – 25 shots it is maybe .5 to .75 low, which is a miss when i am shooting at acorns. With practice I will count my shots and start factoring increases in elevation with shot count.

I was trying to get it to about 900 – 920 fps and just cant get there. I have read over and over how the pellets fly more accurately at that speed. When I reduce the power wheel to about 2 it starts getting more inconsistent and the 18 grain JSBs are still pretty close to 1000 fps. I have yet to figure out what this gun likes. It is a bit pointless to fret on the accuracy. I originally bought the condor as a platform for an archer conversion. I have the kit just need to install it and then I will be slinging arrows baby.

My talon is more accurate so far. Tony worked it. It has taken me awhile to get the hang of this, but I cut down a 1 inch sapling the other day with about 8 shots at 30 yards. I am now hunting the twigs on that sapling. I like accurate guns. Very frustrating when its acts like a shot gun flinging pellets first this way and then that way. Ted calls it a game of milimeters and while I am not at that level, I understand the idea.

POwer wheel works on some not so well on others. Do a search on top hat adjustment you will tune it down some there if you want to. I personally liked my condor spitting out kodiaks around 935 ft per second. The shrouds can be made with many things you can do a search on that as well. I used conduit and washers and springs. Several guys here sell awesome ones reasoably
