Rhino bullets 380 grains for 375 H&H Magnum

Has anyone loaded the 350gr TSXs?: Barnes 375 CAL .375" 350 GR TSX FB

I was wondering if they would have any advantaged in my .375 [Wby, in my case] over the 300gr bullets? Am I right that it would be helpful only in animals as big as buffalo?

Hi Marinehawk.

I have not yet used the 350's, but can tell you that the 300's in the standard 375 are outstanding.

In your Wby the heavier slug would definitely be an upgrade from the standard bullet weight offering, particularly for use on buffalo.

On thinner skinned game you will really need to deliver this bullet where it will meet with the most resistance and dispel the energy, such as the scapular bone of the shoulder.On lung shots, and on smaller game this bullet may only pencil through with little immediate damage.

I would probably not load this bullet for specific use on thin skinned game unless that game was in the Eland/Moose catagory.

If you load them up and give them a run, get back to us and let us know how you found them.

Regards,
Paul.

Thanks Paul. In the short run, I'm hunting brown bear (and smaller creatures) in S.W. Alaska in Sept. I likely will go with the 300gr Partition factory loads for that, but I have wondered about getting some 350 TSXs loaded up at roughly 2,550 fps MV. Because of the relatively-high B.C., that should not fall below 2,000 fps until right before the 300 yd range, and sighted in 3" high at 150 yds, it would hit only 2-1/4" low at 250 yds. In other words, if the TSX will function properly in velocities from about 2,000 fps to 2,600 fps, it might be a great load for medium to massive game. I just wondered if anyone else has used this bullet, and with what results at what velocities.

My .375 has taken nine head of game over the last couple years since I bought it, ranging from Canadian Timber Wolf to Cape Buffalo. All but one animal, the Wolf, fell to TSXs (the wolf was a 300gr Hornady BTSP, just what I had loaded). It's become my default bullet, I've been so impressed with them, I don't load anything else for hunting, in any caliber.

Even at 1,800fps, the 270gr TSX still expands, and seeing as the 300gr has the same nose cavity and composition, with simply a longer shank, it will too. I just bought a box of the 350gr TSXs, and I'm betting there will be no issue hitting 2,250fps out of my 23" barrel. Seeing as I've seen respectable expansion at just 1,800fps in a reduced H&H 270gr TSX deer & Impala load (took this year's Whitetail at home in Canada and an Impala this year, with this load), and the 350gr once again shares the same nose cavity, at 2,250fps it should expand perfectly.

Hoping to hunt elephant in the coming years, the 350gr TSX will be the bullet for sure.

Have had fantastic penetration from the 350grn Woodleigh FMJ's with their high sectional density. Ideal for Elephant and Buff recovery shots.
Advise; Do not use TSX bullets on Elephant. Only Solid or FMJ bullets.

Hi, I made some experiments with the 380 gr Rhino and that is on my site. However, the site url has changed because I lost my domain name. => Swedishhunter.com.

I have not yet hunted with this load but for bigger animals in Africa I think it would be good. The recoil from the load is not big. I do not feel much difference from when I load with 270 gr bullets which I think is beacuse the velocity is low

Oscar,
If you need, I can put you into direct contact with Dr. Kevin Robertson. He is very passionate about ballistics and enjoys discussing it. You will certainly learn a lot from him.

Has anyone got some load data for the 380 gr. bullets in the H&H case using common American powders? I have a couple of boxes of the bullets but don't know what loads to put behind them. Alternately, if someone is interested in the bullets, send me a PM.

I know this is old but BJV wrote that he got 2870 fps using a 286 gr in his 9.3x62! I am surprised no one else commented on this fantastic velocity which must be a misprint. I am sure he meant to say 2370fps which is about right for that round with that weight bullet. 2870fps would yield an energy level of 5230 ft/lbs which is as much or more than the .458 Win mag can muster! Just not realistic.

This year I participated in a buffalo hunt in South Africa. We used a 375 HH with 380 grains bullet from Rhino. The buffalo, hit through the heart, falled down stone dead at the first bullet!! The bullet, once extracted, showed a perfect opening, like a flower, with very high weight retention. There is a manufacturer of ammunition in Sweden (Rhino Bullets), who is providing all configuration (from 235 grains up to 380). Ciao, Obelix.

Hi Obelix,

They're designed and made locally here in South Africa, and marketed internationally around the world.
Most hunting enthusiasts here in SA that reload swear by the likes of them and GS Customs. Both Perform flawlessly and are definitely considered "premium" bullets.

Maybe I picked up this thread a bit late and it might be an after thought! I hunted buffalo with my 375 H&H, loaded with 380gr Rhino bullets. They were loaded to 2150 fps and I had to shoot the buff twice. My first shot was from 90 meters and it hit the animal to far back, I missed the heart and just pinched the lungs but destroyed the liver and splean. it mushroomed perfectly and was found under the skin. My second shot was at 15 meters, between the eyes with the same type bullet. It destroyed whatever it emt and I found it under the skin on the middle of back of it's neck. I shot blue wildebeest with it and shattered both shoulders at the joints and found the bullet under the skin on the opposite side. The max velicity with the 380grainers you'll probably get out af a 375 H&H is 2300-2400. Dr Kevin Robbertson and Mauritz Coetzee know what they talk about. You can trust there input.

Hello, forgive everyone for being away so long, I've changed my destiny and this has made me more messed than usual. I'll take a look at your interesting post and learn from them.

It would be interesting to contact Dr. Kevin Robertson, and I would do a lot of questions, not only on the cartridge 375 H & H Magnum, but the rest of the rifles I have. I would be grateful for a way to facilitate contact. Thanks.

Oscar.

I've heard very good things about the 350g Woodleigh PPs on cape buffalo and brown bear. I plan to load them in my 375 Weatherby to about 2500 fps (well below max in my 375 "Bee").

I had the opportunity to use the 380 grain Rhino in a .375 H&H on a safari with John Sharp Safaris in Zim in June, 2011.

The Rhinos were loaded to ~2,200 fps and, despite the seemingly low velocity, the performance on giraffe was quite dramatic. As my PH (Shaun Buffee) was, at that time, unfamiliar with the Rhinos' performance, I agreed to use them as the first round on three giraffe (followed up by 350 grain Barnes Banded Solids. Later, I tried 350 grain Barnes Triple Shocks just to see how they'd perform. A Rhino was also used on one dry Zebra mare.

The first Rhino (lung shot on a giraffe) expanded to just over one inch. That bullet was recovered and exhibited perfect "four petal" expansion to just over one inch in diameter. Additional recovered bullets included 350 grain Barnes Triple shocks (used on the second giraffe). One Rhino that killed the second giraffe broke off three petals after, presumably, hitting the heavy bone of one of the giraffe's front legs. The wound was just above the heart and was, despite the bullet losing three petals, devastating.

The Rhino used on the zebra was "through and through" broadside and was not recovered. The recovered bullets were recorded in camp in the attached photo.

One more, showing the 380 grain (.375) Rhino (recovered from my first giraffe) next to an unfired one.

Excellent info, A-zone, thanks for sharing.

Hi all,
This is my second reply to this post. I first used the 380 rhino on cape buff in april of 2010. One shot to the lungs, almost full weight retention and mushrooming to a little over one inch. I also shot a huge eland and my wife shot a good zebra, all with about the same results.
I am thinking of using this same bullet and load for elephant in the coming april and wonder if anyone has an opinion on this thought. My PH likes heart and lung shots on eles and I will go by his advice.
Cheers, Mike

I recently had a good visit, with a beer ot two with Dr, kevin robertson of perfect shot and we seemed to agree on the excellent performance of the rhino 380 rounds, only issue is that they are minor imperfections from round to to round, but they do work well.

I can also vouch for the 350gr north fork, have a look you will not be dissapointed.

My best always.
