It looks like the 140 gr is wrong. The Accubond and Ballistic tips usually have the same BC. The 140 BT is .456.

Applied ballistics lists:
140 Ballistic tip .444
140 Accubond .424
150 LR accubond .568
The 150 Accubond is not in the list I have.

Well, a 7mm 140 AB is a BC of .485, and a 140 Interbond is .486. They are always very close. A 150gr .277" Interbond has a BC of .525. So there ya go, the 150 AB will be around .525.

I couldn’t find a solid answer either. Went with the 150 BT b.c. and adjusted velocity to match drop. Verified past 1000 yards. They shot considerably better than the 140 accubonds in my 10 twist 270 wsm so it was a no brained. So far one large black bear was taken with combo, don’t use it much, so not a lot of data but I’m sure they will continue to work great.

Try .525 with yours and see how it goes.
