Anything 1100 FPS or less is subsonic Emp. There’s a bunch out there. Even many target loads are subsonic. I do have over 30k rounds of various SS .22LR if you can’t find what you’re looking for. I found CCI standard velocity and Wolf target to be the most accurate across the board for the money. The CCI has been available for 3-4 cents per round in bulk for a while now up until this last run on ammo. I split a case with someone here last time I found it. Not sure where Nether is but if you can get to my route between Hammond and Baton Rouge, I’ll hook you up.
I will meet you in Hammond and take some of that CCI Standard Velocity off your hands at 3 cents per round.
