Looking for an AB profile for SK Biathlon

SK Long Range and Semi-Auto are the same load, just how they lot test as to what goes in what box.
The AB library has a G1 of 0.159 @ 1100 fps for Long Range. If you poke through the PDM's you'll see the usual 0.125-0.135 G1 ranges.
Lapua polar biathlon has g1 approx ~ 0.149. SK RM is G1 BC around ~.134. IMHO those are different enough you really need to get the correct PDM or validate your dope empirically. I just tested some over the weekend, it definitely is a different bullet than typical match 22LR.
[ETA - I Have no first hand experience with SK biathlon, only SK RM/S+/LR etc.]

Polar is different even from other Lapua. SK Blue box is the same bullet as the rest of their line up, just the faster velocity range than Red or Yellow.
A LabRadar measured 100 yard session today was 0.153 G1 for me, so for 100 yards and in AB's 0.159 is pretty close, if doing longer distances the stuff in the PDM's is going to be closer to reality.
