When one spends $30k USD or more on a DG hunt, the cost of the bullet is immaterial. Nor is there such a thing as a “magic” bullet, pardon the pun. Use a premium grade bullet that YOU have confidence in. I perforated my first buffalo with 7 shots from a .500NE using Barnes banded solids before it tipped over. 5 of the 7 shots were placed in the vitals. For me, I’d use the banded solids again without reservations, but I’m very game to try the Hydros on my next DG hunt. Both Hydros and Barnes shoot quite accurately and function well in my DG rifles. I’m sure either will do quite well on game so it comes down to which of the two is available at the ammo store when I need to replenish the supplies. Availability can be challenging at times depending upon which country you call home.
