Tuning Wildcat 3 mistake already

Please be careful as you rifle is likely cocked and under pressure. Keep your fingers from the trigger

Every time you move your lever backwards there will be a pellet loaded in your barrel so do not try over and over to move lever to front and back. Just pull the lever back as far as poosible ( you feel a spring resistance and you pull till the end of that) and try to remove the magazine by pulling it out. Use a bit of wiggling side force as a pellet in beween the magazine and barrrel might just be blocking it ever so slightly.

when the magazine comes out just bring the lever forward and shoot the pellets out in a safe direction ( pellets will go out like a hailshot) . Shoot a few times without reloading the magazine as it might take a few shots to relase all what you loaded. 
When this does not work and as you are obviously not very aware of the technical aspects of the rifle I would not start loosening anything by yourself but leave it to an technician . These high pressures are nothing to take any risks with !
 
I've never owned a Wildcat, but from the schematics in the Support section of the FX website it sure looks like the barrel system is much like the Impact. The barrel/shroud assembly is held in place by a grub screw just ahead of the magazine area. Back out the screw a few turns and you can pull the barrel and shroud out the front. No need to separate barrel from shroud. Then you should be able to free the mag and check for any loose pellets that fall into the rifle. Look down the barrel, and if you can't see through it gently push a dowel or cleaning rod down from the muzzle and tap out any lodged pellets. Take a look at the breech (brass) end of the barrel, identify the breech seal O-ring near the end, and with a strong light and maybe a magnifier look to see whether the O-ring is cut or otherwise damaged. If so, The O-Ring Store can have a replacement at your door in 2 days. Otherwise, re-insert the barrel/shroud assembly, make sure it is seated all the way and then tighten the grub screw firmly BUT NOT TOO HARD, and resume shooting.
 
The problem with that is the magazine is stuck in so I have nowhere to push the pellets



I have a Wildcat Mk3 and this has happened to me several times. I'm almost positive you've loaded 2 pellets in the barrel and the 2nd one is still partially in the mag, hence the reason you can't remove it. Use the cleaning rod to push the 2nd pellet back into the mag, remove the rod and then remove the mag.
 
Think all advice, so far, is accurate and spot on, my only concern is that the rear Power Wheel was adjusted, possibly incorrectly, at some point in the process. My new Wildcat 3 came with a Wildcat 2 Owner's Manual, so no information, as to correct way to adjust Power Wheel available. Is there any connection between possible incorrect Power Wheel adjustment and this problem?

I agree. No!

Someone above suggested that your problem is one pellet in the breech and one partially in the breech and in the magazine. I had exactly this happen once with my Wildcat MK3 Compact and the solution was exactly as JohnnyRambles suggested. Push a cleaning rod (or wooden dowel) carefully down the barrel and push the pellet(s) back until you can clear the magazine. When you feel the pellets move pull the cleaning rod/dowel back a bit before trying to remove the magazine. If you can’t get this to work then remove the barrel. 

The videos show you how, but here is a condensed version:

Remove the cheek piece at the back to the Wildcat. It is help in by 2 screws (I believe that they are 2.5 or 3mm hex). You will then see two screws on the front part of the block, in front (i.e. towards the muzzle) of the magazine. The front (smaller) one is the screw holding in the barrel. Loosen this a turn or two. No need to remove it completely. This should allow you to pull the barrel forward out of the gun. Sometimes the back screw/plug is tightened down so much that it actually also holds the barrel in place. Loosen this one turn. It may have some form of thread locker on it so you may have to use some force. If my ,memory is correct this uses a 4mm hex , but in any event it is bigger than the front barrel retention screw. Again, no need to take it out. Then pull the barrel forward.

Replacing the barrel is simply reversing these steps. One note when replacing the barrel. Push it in until the notch at the bottom of the barrel fits into the corresponding pin in the block. However don’t jam it in. Check that you can insert your magazine without too much trouble before tightening the barrel screw. It is possible to push the barrel so far in that the mag will not be able to be inserted. Sometimes I put the mag in before I actually push the barrel back for this reason.

Good Luck,

Thanks to everyone for the great support and quick responses. 

I was unable to open any of the videos. They kept giving me a 404 error in my phone and computer. I guess I am too stupid to figure them out.

All ideas were great. Johnny Rambles has the most simple solution so I tried it. I got a cleaning rod and shoved it down the barrel then I "wiggled" the magazine out.and ran the rod down the barrel. It was pretty hard to push so I added force until t pushed the pellets out. there were probably 4 in the barrel and one flattened in the magazine. I think I only cocked it partially initially and thought I had missed catching the pellet so I cocked it again and I think this was my first problem. Then while I was trying to free the cocking lever I apparently loaded more pellets.

I don't think I had a problem with the power wheel but I will look for leaks and get my chrony out and check speeds at the various numbers to make sure it works.

What type of oil should I use as a lubricant?

Thanks again everybody!
