I have that Berger DVD, most impressive! I also have the Handloader article rbergum95 mentions & it is very informative. I have also been reading results from various longrange forums & from people I trust & to me the results are overwhelming, enough so that I am going to load some for my M700VS/308 & hopefully harvest a WT or 2 next season. For a 30 cal 168 gr, the BC is impressive @.512.
700xcr, the 150gr. 270 info does look good, but I am getting extreme accuracy with the 140 Accubond & the BC is .496, higher than any 140 gr. presently avail. that I am aware of & for some reason that bullet has a much better BC than the BT of the same weight, which is usually not the case. Since I would not be able to push the 150 Berger as fast, I don't think it will be flatter or buck wind much better until 600++ yards, which I would not want to shoot an Elk that far with a 270 anyway, plus the Acc. is bonded. Have you tested it, just curious?
Anyway, I hope to range test the 168 Berger in late Jan, I hope my rifle likes them.
