Not an easy job to promote (relatively) new ammos.
In my perception, quite a lot of hunters are living a dream about keeping alive the tradition of safaris of lore. Consequently they want to stick to ammos used in the great past time of African safaris of the 1940, 1950 an 1960. That let little oxygen for new ammos even though they can be more efficient ant practical.
More over, safaris are big money and a hunter isn't too inclined to experiment new options. But I have to bow to the indomitable need of American hunters to test at any cost new rifles and new ammos, even jeopardising a safari. Long life to passion!!!!!!!!!!!!!!!!!!
