Range Report keeping it sonic

[OldmaninNeb]

I don't know if this is the place to even ask this, but is there a place with tables etc. that would give a person an idea of fps in 100 yd. increments? Like how far can you shoot a .223 before it goes subsonic? If i SUPPLY the 10'velocity thru a crono, what is it @ 300 yds? 600 yds? 900 yds?
Thank you.

Just remember that wind drift starts getting funky at Mach 1.2.

And different bullets "tolerate" transsonic velocities better than others.

I haven't been able to derive any hard and fast rules on this, either.
