Put some groups on paper yesterday. Light wind under 5 mph.
Dismal...
I have five different pellets and tried them all. I have more varieties coming.
Anyway, I was going to start at 25 yards. but the test group with the gun is less than .2" at 20 yards and NSB has the same gun and is shooting sub 1/2" at 50 yards. So I set up at 50 yards.
I do not have a quality bench like OS OK constructed in his thread but a commercial "portable" bench make by Caldwell. I have shot sub MOA groups from it. Here it is:

Groups were 1 3/8 to 4" at 50 yards. I am not too shabby behind a trigger so it is not me. I wondered if the suppressor may have been clipping the pellets so took it off, and no significant improvement. Next step is to change out the scope.
I had mounted a cheap Tasco 4-16 I had lying around. I cannot remember which gun I took it off of, but it may have been a .22 Hornet Handi-rifle (and that gun would not shoot either..?????). I sold it about 10 years ago. There is a Vortex Razor HD 5-20 mounted on my long range rifle. I have not got used it yet. so no loss of zero to deal with by removing it. It is a high end scope and should take that factor out of the equation.
BTW, nice not having to police brass, or wear muffs. Filling the gun from the air tank is a bit of a PITA as the pressure gauge is under the forearm. I am thinking about making a cradle affixed to the shooting table that will hold the 75 cut ft SCBA tank and that allows me to keep the tank connected to the gun. I would still need to fill the rifle when needed but I would not need to use the QD and bleed the fill line after every fill. Should save a bit of air by doing that as well.
