 The ballistic performance had to be close to or equal the performance of the .375 Holland & Holland Magnum.The 8×68mm S was chosen as parent case, since it offers enough case capacity and a competent gunsmith can relatively easy rechamber a standard Mauser 98 rifle to accept 8×68mm S based cartridges.To keep costs down and promote an acceptable recoil level blowing out the parent case was renounced.
