I haven't really gotten a straight answer on this one, but here goes:
My current "long-range" build is a 16" AR shooting M193 at 3168FPS and IMI 77gr OTM's at 2774 FPS. The rifle shoots 1 MOA and has a 1-6x LPVO.
I've got Strelok and know my holds, it's just that I don't know what the range is for pinging steel versus what the actual effective range is for fragmentation, yaw, etc. Most people say ~2500 FPS is minimum frag for M193 and ~2200 FPS for 77gr OTMs. In that case, 250y seems to be the maximum effective range for my 16" rifle to reliably fragment/yaw/wound etc.
I want to learn how to calculate this myself, as I've got an 11.5" build that I'm also curious about. What is the absolute minimum velocity/energy that a .22 bullet should have to do *anything* or not be tossed around too much by the wind?
