I will go out on the proverbial limb and say that this bullet can't have a G1 BC of .829, That is higher than ANYTHING Berger makes in ANY caliber including the 230 grain 30 cal and 300 grain 338 cal.
In order to see a BC of .8+ one needs to go to lathe turned, heavy .338s and .375 from vendors such as Cutting Edge.
I don't know where they came up with the fairy dust to boost the BC by .229 over any of the very best VLD bullets out there!
Keep us posted.
