This relative newcomer was introduced by Kreighoff in 1996 as a way to bring the 416 to double rifles in the British way. With a 410 gr bullet at 2300 fps, pressures are sedate and the gently sloping case means that loading will be easy. The headstamp on these cases although not Bertram were made in the Bertram factory to the same standards as his other brass. The price is for 20 cases and the shipping weight is 450 g.
