I have tried many types of ammo through this gun and at 20 yards I can not get this thing to even group its just spraying everywhere... I am begging for help. I was a expert qualified shooter in the army, can make 2 inch groups at 500 yards with a rifle. Trust me the first thing I checked was myself and of it was me the shooter I can assure you that is not the case. This gun will not shoot anything accurately other then JSB pellets. I'm begging for a solution thank you in advance.
Air Venturi Avenger .25 horrid accuracy

Lots to look into. First, the magazines generally suck. I use CARM mags as they are more dependable. Also try single shot loading till you figure out the gun. Next, the tune. Factory reg setting probably pretty high. You can set as low as 1400psi and get good results. Next, the hold. If you have the plastic stock, it's very flexing and will contribute to wandering shots. Lastly, the ammo. The Avenger shoots pellets better than slugs due to the type of barrel and twist rate. It doesn't do slugs well at all. I have great results with my 22 Avenger using 1800 psi reg setting, 2 3/4 turns on hammer adjuster and head sized and weight sorted H&N 18 grain Baracudas. They shoot at 884fps with ES 5 and SD 1.5.

This is not even close to being a slug gun. I'm so disappointed. I am going to adjust the regulator down and hope for better results. Now is there such thing as a break in period I have run about 200 shots through the gun.

Get an aftermarket barrel support device such as the Donny Fl adapter. I bought a different kind off eBay. Get one that actually goes over the end of the barrel. I absolutely hate that part of airguns. The damn barrels end 5 miles short of a stupid shroud and they are supposed to shoot perfectly centered through 500 different hoops before they exit the muzzle

Mine has a Donnyfl adapter on it. Shoots JSB 33.95 @ 883 ave SD 1.3. 1/4" group at 50 yes. Reg is at 2800 and hammer spring is 4 turns in. Only get 10 shots per fill

Are you trying to shoot slugs out of it, or good quality pellets? Get it going good with pellets first; this is the typical preferred ammo for air rifles. Find out what pellet others seem to be using.
Is the rifle new or used? Have you made any modifications?
1. Inspect baffles in shroud for foreign debris like plastic chips, mold flashing, lint or fibers from cleaning patches or felt cleaning pellets.
2. Further inspect center holes in baffles and shroud exit orifice for signs of clipping - where a tiny portion of the pellet is hitting. Scrape or drill out holes.
3. Remove shroud and see if accuracy improves.
4. Inspect muzzle/crown for any discontinuities (probable will require doing #3 or disassembly), particularly the crown, the last surface the pellet touches. Look for a burr, any buildup of gunk or led right at the very end of the rifling. You can touch up the crown using a round-head brass screw in a drill with valve lapping compound.
5. Push a pellet throught the barrel slowly, using a dowel rod, and inspect it after it comes out (may require removing the barrel). Is it uniformly engraved all around by the rifling? Look for any ragged gouges that might be caused by a burr on the rifling lead-in or air transfer port opening at the breech end.
6. Inspect barrel breech end and said surfaces in #5 and smooth out anomalies. If you plan to keep the rifles, polish the barrel 200 strokes with JB bore paste and nylon brush, taking care not to touch the crown surface with a metallic rod.
7. Push a pellet through just the magazine manually with a dowel, and see if is being damaged or deformed. Check each magazine chamber.
8. Shoot a few rounds point blank through a clean white paper and look for splatter evidence of moisture (in your air), grease, lead particles, etc.
9. Check all mounting screws in your optic/sight. Check rail attachment and receiver screws to be sure they are all tight.
10. Contact your dealer for further advice or replacement if you don't want to do any disassmbly or cleaning yourself.
Good luck!

If you are referring to the post above yours that shot count would be expected. The reg is probably set a little higher than needed and driving 34 grainers at near 900 the gun is flat out maxed to the max. I’m actually quite surprised it is even capable of producing that energy. Of course he will get no shots.

He said it shoots pellets just fine. Slugs take more work to figure out and some barrels just don't like them at all. Out of the many guns that have passed thru my hands the only one that would shoot pellets and slugs equally well was a Charlie Frear tuned .25 Cricket.

All i can say is how mine is setup, I have a FL barrel extender, I have replaced the original barrel band with Black Arts design barrel band and a lock down barrel band near the muzzle. Mine loves slugs. remember slugs start to shine i have found,, 50 yards and farther. Pellets 50 yard and closer

If your getting decent crony results, I would start looking at things that might damage the ammo.
single shot loading is good start. Possibly pulling shroud baffles for a couple shot?
also…visual inspection of barrel, pushing a pellet though it see if it comes out damaged. I’m not to familiar with avenger barrels, but pushing a pellet though it can tell a story.
