It's not that easy. It's mainly about the cartridges 11,2x72 Schüler and 12,7x70 Schüler by quick reloading of the rifle. I used both for Big Game hunting. The cartridge 11,2x72 Schüler is extreme because the cartridge is wide compared to their rim. At times a cartridge jammed. The cartridge 12,7x70 Schüler is easier to reload, but there were still problems with reloading. I shot an elephant with two shots made quickly one after the other and did not notice that a cartridge was between ejected from the magazine. The trackers gave the unfired cartridge back to me.

It's nothing new, everything is known and that's why the cartridge 425WR was held in the magazine of the original rifles with clamps.
