10,3 x 68 RWS "smart magnum"


RWS has developed a “new” round based on the 404 Jeffery with a belted case shortened to 68 mm and necked to 10,3 mm, same bullet diam of the swiss 10,3 x 60R

They say it is made for use a large variety of bullets raging from 170 to 400 grains.

I’d say that the concept is very similar to the old 400 A-Square, although I would say that developing a long belted cartridges nowadays could not be a “smart” idea


A belted case based on the .404 Jeffery is a contradiction.
