The solution to the belted case problem had been created in 1915 by Charles Newton: the .35 Newton, which holds five more grains of water than the .358 Norma, has the same over all length as the .30-'06 and has no belt. Charles "Bwana" Cottar used it extensively in Africa. (See "White Hunters: The Golden Age of African Safaris", by Brian Herne)

.30 and .35 Newton cases can be formed from 8X68S brass.

One of the main problems with the cartridge was that it was only available in the Newton rifle, which was too light for the cartridges and had a stock which was prone to split with repeated firing.

Cottar also complained that the magazine floorplate had a bad habit of coming open and spilling ammunition on the ground at the worst possible moment. This is a little difficult to believe, since the follower spring in a Newton rifle is not attached to the floorplate, but to the magazine box. Cartridges cannot be removed from the magazine by opening the hinged floorplate, unless the follower spring is detached from the magazine box as well.

In any case, altering the floorplate latch so that it would not open unexpectedly would not seem to be beyond the abilities of hunters in the field. Duct tape, or its turn of the century equivalent, comes to mind.
