Poor grouping

Hi guys I have a3yr old air wolf I know it needs a service but it's become inconsistent velocities on chrono are up and down it will hit smack on one shot then drop low the next ? It's not what I expect from such an expensive rifle my mates have hw100s and never had them serviced and still pellet on pellet . Anyone else had this problem. Alb robo .

Obviously try multiple pellets through it before you judge the gun, if you have not done that firstly of course.
Clean the barrel out and then commence testing again. My MK3/4 was showing anomalies like you stated and I was thinking it was the rifle even after a full service with certain brands of pellets and then after a lot of time on the range I narrowed it down to just a couple of types and the grouping increased to one on one and the variation on the pellets velocity became more stable.

Yes as Cumbrianwolf commented... try a good barrel cleaning, check breech/barrel o-ring and test a few pellets.
If the chrony continues showing erratic numbers I would give it a full tear down and inspect some parts.

Hope you get it sorted!

I bought a new 177 airwolf was that pleased with it I bought a new 22 as well, I have had nothing but problems with the 22. From new in box it had air leak plus safety tab was broken off. Sent back to daystate, they repaired the leak and tab. But grouping at 2 inch at 39 yard. I have sent it back to daystate twice since due to accuracy but they keep sending it back saying no fault found. My 177 is one hole group at the same range. I have tried fixed rest trialed loads of different pellets cleaned the barrel numerous times. Daystate state they test it with sovereigns so I bought a tin and they are even worse. The best are JSB 551. Daystate also sent me back a small bag of sovereign pellets and they are different to the ones you can buy. But still not accurate. Any advise or recommend a good airwolf tuner would be appreciated.

Have you tried it fix rest without the stock. My .177 is a bit finicky about the stock screw tightness. It even looses it's accuracy if I attach a Rowan hamster via the stock screw.

May not be this but it's worth a try, I pretty sure Daystate test grouping without a stock.

Thanks I’ll try it next time I go to club, if it is that what’s the cure I can’t use it with out a stock. You would think they would test them as they are meant to be shot with the stock on.

Try without it so tight but not too loose to cause it to move. Not saying it is actually this but if you try you know where to focus (or not)
