Have never used these so can’t comment on their suitability for NZ game, but usually any bullet ex Nth America that wears the “trophy bonded” tag is a very tough projectile designed for big tough game like brown bears. Think something that is going to kill you if u don’t get in first. Usually too tough and non frangible for NZ game, even tahr.
Remember Dulley is being paid by his sponsors to push their gear.
The info from @Husky1600 does however sound promising and these pills may not be as tough as others
