I am hearing rumor that these are not going to be out as soon as originally thought, but for good reason. Berger may be redesigning the bullet, as the bc isn't up to par compared to the other EOL offerings, and other heavier 6.5 bullets out there.
I can understand this, as several have said, it's not like the 195 7mm EOL or the .277 170 EOL, where it is in a so called league of it's own, with very little that even comes close. As they stand, it is an improvement over most other hunting bullets out there, but the improvement is marginal, and not enough to convince enough shooters to switch or build a rifle just for this bullet. It would probably be somewhat of a flop, and I would also see it as a limitation for Berger. Their EOL line is their top dog, the heaviest, highest bc bullet they produce for every caliber they make. In the .277, they went well beyond the standard twist rate and 20-30 grains heavier than any other long range bullet produced for your "standard". 277 rifle. In the 7mm, they did the same thing, going 15-25ish grains heavier than any long range bullet for standard twist. To make a bullet designed around the limitation of the "standard" twist rate for the 6.5, in my mind anyway, would be cutting the EOL name short. And on a second note, alot of the original 6.5x55's were 1:7 twist anyway.....lets go full circle.
It is going to be hard to stand apart in the 6.5 bullet line up, as there are so many good offerings out there with very good bc. The only way I see them breaking from the crowd is if they make a 155-170 grain bullet that requires a 1:7.5 or 1:7 twist, the route sierra went with their 150, accept even more so. A G7 of .355 or higher, G1 of .695 or higher, would do this I believe. Keep in mind, Berger averages their bc. If you average the bc of the 147 eld-m and 150 Sierra in the way Berger does (apples to apples) you come up with about a .335 G7 and .665 G1 on the 147, and the Sierra 150 G1 comes out to just about .690, and I don't see an advertised G7 from Sierra. That 147 bc is worlds different on paper than the advertised .351 and .697, but hey, thats advertising.
But if Berger really wants to step up on the 6.5 game, and do something like their other EOL bullets that require special twists, they are going to have to get away from the 1:8 twist. Just my opinion, and I hope to hear news from them soon!!
