Its claiming 30-06muzzle energy.
That claim of 30-06 speed ... well I would not believe every thing I have read.
Their "true" but slightly dishonest and misleading advertising compares the
muzzle energy (not speed) of a heavy ML bullet to a light 30-06 round. Of course, down range ballistics are totally different and the ML in no way matches the 30-06.
Got to take those manufacturer's claims with a BIG grain of salt.
