OAL and G7 BC of 123gr AG bullet?

[towerofpower93]

Updating StrelokPro for my 6.5G and can?t find the OAL and G7 BC of the 123gr HPBT bullet used in the Hornady American Gunner ammo.

Planning to load 123gr ELD-Ms into the cases once fired, but kinda want to see what this will do at a local belly flop match out to 1250yds while I still have ~150rds of it left.

I know I?ve seen it posted here before, but searching on a phone is bringing me back no useful findings.

Thanks in advance

Factory OAL is 2.235

Thanks much.

That .450 G1 BC seems pretty optimistic.

Wonder if anyone has bought these or pulled an AG round apart to get the OAL.

Well the .450 G1 BC might seem optimistic, but the very similar Sierra 123 gr HPBT shows a ,510 G1 BC (OAL 1.295") and the Nosler 123 CC also show a .510 BC. (OAL 1.200"). Lapua's 123 gr Scenar show s a G1 BC of .527 (OAL 1.298").

In light of that Hornady's BC seems quite reasonable in fact.
