Q:

Help my condor @ 100 yards

Ok, few questions for you guys. I finally got the machete out and cut a 100 yard path so I could shoot long range with the condor. I am though, having some trouble grouping that far away.

FIrst off, how many shots do you guys get before you need to refill while shooting at 100 yards? I know a slight pressure change is much more dramatically noticed at 100 yards, so how often do you fill?

Best I have done so far is about 2″ for 5 shots. I had a few 3 shot groups go in a group a tad under an inch, which is about where I want to gun to be shooting, but then the next shot will be an inch or more low. This makes me think the velocity is varrying enough to cause that. Left and right it stays pretty dead on, wind is rather calm.

I don’t believe I’m the problem here. Even on my off days with firearms, 1″ is pretty big, so I don’t see why the condor would be a whole lot different.

So something is causing velocity changes in the gun. What is it? The valve is good, I know that, so it has to be something in the tube. Any ideas?

I havent shot much at that range , due to lack of range! 😀

But 2 -3 weeks ago , I did take it out to the range , and I was hitting 2inch clay pigions (stationary of course) at what I guessed was 100 yards . but after I laszed it , it was 117 yards

MY power level was set on 12-13 . I would hit about four in a row then my point of impact would drop.

I corrected my MOA and I would hit 3 or four more and again my POI would change.

I came to the obvious conclusion that as the pressure dropped in the bottle so did my POI.

So what i think it needs is a regulator to control the amount of air per shot and im going to order one soon from JDS airman when I get the chance.
kind of like a reloader that would make the weight exactly the same.

The other thing I think might help but I havent tried it yet is to lower the power setting to 5 at the most maybe even start at 2 . with the idea of getting more consistant shots by useing less air . I dont have a close by range so I cant say for certain but it would seem logical.

I belive I was useing 32 gr ein juns

I by no means can claim to be a pro with these rifles but I noticed a drop after 10 shots in POI. I started with 2700psi on power wheel 8 and just topped it off after 10 shots.

I notice that air rifles are more sensative to movement than a powder firearm and I don’t know why but staying perfectly still matters a lot more than with the .308.

I noticed that mechanics played a little less of a role than with a powder firearm and this probably doesn’t help you much but just something I noticed between the 2.

First off, I would make sure the group variations are actually coming from a velocity variation due to the gun:
1. weight the pellets you are going to use and eliminate the bad ones.
2. shoot two pellets off target to eliminate any mechanical “variations” in your gun (offset springs)
3. use a chrony to mesure the speed of each pellet as you shoot them for your groups.
This process will tell you if it is actually the gun and eliminate the guess factor.

Update:

I found what may be the problem. Took the gun apart, and started looking at the hammer. It’s pretty well chewed up, but then the derlin guide pieces just fell off the ends! I’m thinking this may be causing issues, if it’s coming apart like that in the gun as the sear may be pulling it off and such, that could cause some variations in velocity. You guys think this may be it, or should I be looking at something else?
