HELP Air Venturi bullpup .25

[Wordplay341]

Issue is, past 30 yards my groups aren't even respectable to call a group. I've tried everything different ammo, hammer spring, and Regulator even drilled the moderator to take clipping out of the equation. Is it just a fluke of a Gun because I've watched multiple videos of the same gun and caliber put 1½ groups at 100yards. Picture is 8 shots at 60 yards. I own a air venturi avenger rifle .22 woodstock and I've put sub moa groups at 100 love that gun

Need more info like ammo and speeds. Mine shoots baseball sized groups at ~55 yards even at 1000fps with a 22 Hades. Turned down it shoots under moa, but 1.5" @ 100 yards is going to be tough to do with pellets.

On a windy day that might be a good group. My full length Avenger shoots FX 25.4s great at up to 35 yards but the one time I tried it at 100 it was large discouraging groups. But it was windy and I'm pushing them about 930 fps. Before I slow them down I need to try it again. Hopefully under less windy conditions. I'm also trying to learn to read wind better but that seems like a long term project.

Are you using a 1/2x13 adapter for an after market moderator ? The factory “moderator “ does almost nothing and it does not support the end of the barrel like the adapter, also a barrel band support helped me I believe.
