Q:

Help! My Edgun lost it’s mojo

I need help!

My Edgun R3 (.22 standard) has been hitting it’s target absolutely perfectly, until now.
It started spreading it’s bullets, at 50 meters it’s an inch here, or half an inch there, then all of the sudden 5 bullets hole in hole (which is normal for this gun) then an inch in some direction, i.e. totally erratically.

Cleaned the barrel, re-seated the gun in the stock, swapped ammo, checked the scope mount, no change.

So what to check?

Could it be clipping? Is there any videos on how to get the shroud off easiest way? Is there a way to loosen the barrel and re-seat it?

Arrrrggghh it was shooting SO well, was shooting beer cans hung up in a string at 75 meters, not aiming at the can, I had the goal to shot the string off the can instead, and now this…

I should add;
Putting on a scope cam and I think I can see hints of spiralling on the shot’s going wrong, I tried various HST settings just to try to make a change but it did not help, So that’s why I wonder if it could be clipping.

We all know that it’s an impossibility to shoot 1500 pellets and have them all in the same hole at 50 meters. But after 1500 pellets you should have an idea of the accuracy in your hands and be able to tell when there is a flyer that it’s something other than you.

There is a very good chance it’s the pellets. How many times per 100 shots do you feel the shot is outside what you know the accuracy should be in your hands?

I do a fair amount of slow motion video and I do see some pellets spiraling once in a while.

I’ve seen changes in the # of spiraling pellets coming from different lots of pellets.

I wouldn’t take anything apart until you’ve ruled out the pellets. If you start changing multiple variables before ruling out others it’s going to be tough to know what’s going on.

Try to remove the front tube 1st, the one covering the shroud, it takes some tries but a rubber glove helps give a better grip, once that is off than you need a 19mm wrench and that shouldn’t be a problem.

And how to remove it best way? I tried with heat but without success, its tighten down -hard-, best tip?

You need to shoot it without the shroud 1st to make sure its not clipping, than you take it from there.

Thats the thing, low mps should not spread in all directions either but something is triggering the spiralling…

Check those things i said. Barrel torque,clipping and stock/airtube interface.

Can you catch a few pellets in a 5 gallon bucket of water to get a look at them? Did anything appear different since its return like the shroud/air reservoir gap/alignment at the knurling? May not show anything but I am trying to think of easy things to narrow the problem before re-tightening the barrel/shroud, messing with the reg, etc.

O.K. I never paid any attention to that the mps varies that much. It shouldn´t come off the reg before down at 130 bar, at least.

If it didn’t come off of the reg then the reg could be the problem.

I clean using cotton tabs, its really clean

However chrono test showed the cause most likely

It was a bit strange,

This was not from a full fill so it might have come off the reg in the middle here but still, those spikes/irregularities seems strange, will do a full string tomorrow

Got a total of about 1500 pellets through it

Been there,done that! I bet it´s either incorrectly tightened/torqued barrel or clipping. The muffler housing shouldn´t be hard to remove,at all. Try this : Get a piece of an old bicycle inner tube and clip a suitable size section that you use as an gripping aid. You can alsohave that rubber wrapped around the housing and take a piece of leather over it and use universal pliers and twist. It will come off.
Once removed you need an 19mm open end wrench and a wise with padded jaws to place the breech in between while you crack the muffler loose. The barrel is more likely sitting loose – it´s threaded into the breech end.
If clipping is the problem you need to drill the baffles out to 8mm or so to fight that.
There is one more possibility though – incorrectly torqued action to stock connection screw. It can distort the airtube/barrel interference. I bet one of these is the culprit. They´ve been throwing your gun around during parcel.. :1:

How did you clean the barrel?

Did you chrono it?

I had to ship it back to reseller due to regulations (to get my license for it) so it could have been bumped, nothing visual though, but I cannot say for certain.

(it was well packed but I cannot guarantee reseller did not do anything to it)

I’ve tried to get the front shroud cover off but no luck so far, it’s well seated and you aint getting a good grip to start turning it either..

I really dont know… could almost feel your pain and frustration from reading the title.

Why would it start clipping suddenly? Did you take it apart, knock it against something?
