Stid, if you're hoping for the advertised BC of the 308 210's (.730), you're going to be a little disappointed. The actual G1 BC is a lot closer to .63, same as the 210 Berger and 208 A-Max, not surprising since they are very similar in shape and length. An LRH member did some extensive testing and I witnessed one of the tests as well set up my acoustic SuperChrono under 1005 yd target to measure velocities down range.

Another LRH member from Alaska also did some fairly extensive testing and came up with the same results.

The .308 190's are advertised @ .640. If the 210's are actually .630, the 190's will not be close to ..640, probably closer to .540.
Another member, the guy from SC who used the 175's for deer hunting, confirmed the 175 ABLR's advertised BC to be correct. Once agin not surprising as it is very similar in shape and length to the 180 Bergers which have a similar BC.
Don't have a clue why the 7mm 175's are accurate and the 308's are so far off.
