It can only be two things,right?

Thoughts, Shooting my Maurader Field Target.22 using Air Arms Diabolo Field 16 grams I get all pellets touching at 25+ yards.
Next day my groups are opening up....So my air pressure went down ,could that cause my groups to open up ,I mean it was not a big drop ,but it was getting down to 1000psi which I think is too low.What is your sweet spot? I think I keep it above 1500psi from now on.
Ok, the other problem could be me,I am not as good from one day to the nest:cry:

Atmospheric conditions? My guns were all spot on, stacking pellets in the cooler weather. And when the weather warmed up and the air thinned they can't group on a paper plate. My marauder 25, dreamline 25 or impact 22. This is at 92 yards. They're fine at 50. I can only guess air density.

Don't have a Maurader Field Target .22. AFAIK, the Maurader isn't (usually) regulated so you would be dealing with a balanced valve and the power curve...

Too much pressure and the valve doesn't open fully yielding a low starting velocity.
Then, as you shoot, the valve and pressure work together and flatten the power curve for some number of fairly consistent shots.

Once you are off the flat part of the curve, the velocity drops (rapidly with small capacity reservoirs, slower with large ones) with every shot.



Regardless of how the Maurader is setup, I would plot the power curve. Do a fill and quick barrel cleaning, then shoot a string of pellets (from full to minimum pressure) over a chronograph and graph the numbers to see what is happening.

I plot the power (curve) of all my airguns when new to get a baseline. Then again when broken in and occasionally after that to check what's happening. That way I can see if something changes and can investigate.

Hope this helps!

Cheers!
