Lapua Scena 338 300gr bullet ballistic coefficient

[trazman]

Hello I just started using 300gr scenars in my .338lm. I wonder which ballistic coefficient should I use. On their page it says that the G7 BC is .368, Litz says that G7 BC is .392 and ultimately I use the BallisticsARC APP that has the bullet in its library, but it says the the drag function is CD?? and there are 32 different coefficients based on different velocities.... I will definitely found out with some shooting, but since the Scenar is a common bullet I hope someone already knows the exact data.

Thanks, Tomaz

I recommend going with what Litz says. He hasn't let me down yet!

Tomaz, he man, good seeing you in Vegas... did you get this question answered? If not, I would be happy to help with the CD stuff.
