well you understand wrong, its the twin to the 257 roberts, the 06 has a 200 fps advantage over it,
I don't think so. Not according to just about everything that's ever been published about it. They all say that it equals the 06, which it what it was designed to do.

Looks a lot closer to the 25-06 than the 257 bob to me.
