Load Information For the 500/416 NE With Barnes 400 Grain TSX Bullets?

[UpNorthMI]

I purchased my first large double last year, a Krieghoff Classic in 500/416. It shoots well with factory ammunition and I've collected a reasonable amount of load data for the caliber other than loading and using Barnes TSX bullets. I've even come across a number of unclear negative comments (pressure?) about using Barnes TSX bullets in a Krieghoff double.

I'm looking for feedback from other 500/416 users and reloaders specifically about using & reloading the TSX bullet for this caliber.

You may ask why use the Barnes TSX, the key reasons is availability and the positive experience I have had with them in .375. If I could get my hands on 400 grain Swift A Frames in .416 I would happily load and use those. Anyone have any for sale? I have a trip planned in May to Australia with my son that includes a large amount of buffalo culling, other than solids my factory ammunition includes Nosler partition and Hornady DGX -B bullets.

I have load data for a number of bullets but not the barnes TSX, so I am going to be interested in what others have found works for them.

400Gr Barnes TSX
Nosler Cases
Federal 215 Primer
107.0Gr H1000 powder

Velocity= 2320 FPS

400Gr Hornady DGX Bonded bullets are excellent water buffalo medicine, and I’d be more than happy to provide you with load data using these bullets if you like.

The reason Barnes TSX & other monolithic bullets are discouraged from being used In Kreighoff double rifles, is because Kreighoff themselves do not encourage firing too many monolithic bullets through their wares since they believe that it wears out barrel life comparatively quicker than lead cored bullets. Unlike say Heym, who have absolutely zero issues with how many monolithic bullets you run through their double rifles.

Thanks for your comments, from the load data I have picked up (mainly from old posts on this forum) it seems that 105 - 106g grains of H1000 is typical for lead cored bullets, the only prior load data I found for a 400 grain TSX was for 96 grains of H1000 giving 2,300 fps (Member Jim G900) considerably less powder than recommended for a 400 grain lead core bullet!

I am concerned at the significant variation in power levels on the very limited TSX reloading data that exists for the 500/416 NE, I'm not going to mess around with load development if there are good alternative loads available for a reasonable performing bullet.

At this point I'm going to respect Kreighoff's view on barrel wear and stick with lead core bullets for my 500/416 NE Australia trip. I did a little more research on the newer model Hornady DGX Bonded bullets and agree with your comment that they should make excellent medicine for Australian buffalo. Our upcoming culling trip is for at least 30 buffalo between the two of us and a bunch of camel, donkey and other animals. I will certainly be able to give some real world feedback on how the Hornady .416 400 grain DGX bonded bullets perform. The great thing is that the Hornady bullets are available and also come at a reasonable cost.

I'll be loading some Hornady bullets this week and will see how they perform in my double rifle.

In addition to the Hornady DGX Bonded bullets, I may try some Nosler factory ammunition that I have in solids and partition bullets.
