Range Report Berger 6.5mm 156 gr. Is it dead or still in R&D ?

That's actually not too bad...
For the juggernaut it's shooting, no not at all. I was speaking comparatively in terms of speed, or: 2850 etc.
I was comparing it to my 140 factory Berger, and they are identically looking. They must have just seated the bullet inside the case more, thus less powder.
