Sorry to post again on this subject, there are a number of similar threads. Yet again people want to shoot down the Hornady DGX Bonded bullets based on the problems the old non bonded bullets had.
I would like to add some real life feed back from May 2025 regarding the use of Hornady DGX Bonded bullets in .500/.416 NE 400 grain loads that we were shooting on a large buffalo / camel / donkey cull hunt in Australia.
I selected the Hornady bullet due to time limitations and it's availability, I was unable to obtain Swift A frames or lots of the other possible brands. Barnes TSX were available but load data was not really available or clear. My double rifle is a Krieghoff, apparently they do not encourage the use of monolithic bullets.
I developed my loads by chrono graphing Nosler Partition factory ammunition for velocity, the Nosler rounds shot well and regulated well in my gun. I then loaded the .416 400 grain Hornady DGX Bonded bullets to the same velocity, approximately 2,320 fps, these loads regulated well in my rifle. I sighted it in with an RMR red dot sight and took my new to me double on it's first hunt.
My son and I fired 33 rounds from this gun on our hunt, 1 round to check the sights. My son was shooting a Blaser R8 in .375 but would borrow my double for some use, he missed with his first shot on a buffalo as he pulled high forgetting the "poor" trigger pull of the double rifle, I had one shot that hit a tree on a running buffalo shot, the other 30 rounds all hit what we were aiming at, I believe that the double rifle accounted for 18 buffalo, 1 donkey and 4 camels. 7 animals were shot twice the other 16 animals were 1 shot kills. Total animals shot with Hornady DGX Bonded bullets on this trip was 23 animals.
In simple terms my double rifle had shot magnificently, out to about 90 yards and the performance of the .416 400 grain Hornady DGX Bonded bullets could not have made me happier, the recovered rounds showed amazing controlled expansion, reasonable weight retention but overall these bullets proved to be accurate and show real effective knock down power. I tend to shoot fast and often get that second round off before the animal has a lot of time to react, the very high number of 1 shot kills was based on the fact that the rounds just knocked these animals down real hard.
I've just added a .416 Rem Mag bolt gun to my collection and the Hornady .416 400 grain DGX Bonded bullet will become my go to ammunition for future general use on animals such as buffalo.
I hope my comments help other hunters who are facing ammunition selection decisions and have heard all the prior problems of the non bonded Hornady bullets. I'm not saying that the Hornady DGX Bonded bullet is the best in the market but it is very capable and should be considered.
