Home Forums Hunting & Shooting Africa Buffalo bullets

Heading to Africa for buffalo. I’m planning on using my m70 CRF 375 RUM with 300gr fail safes. I’m looking hard for a left hand 375 for my dad.... can’t find a CZ so may have to get a Ruger in 375 Ruger. I will probably load his ammo too but if it shoots the factory ammo I may just use it. Is the new bonded 300 DGX bullet worthy? I’ve read a lot of negative reports on that bullet but I think they are all from before they bonded that bullet. Any info appreciated!

Any one with a left hand CZ 375 I’m looking. THX

Big 5 hunts are spendy. Use quality bullets. Barns and Swift are highly recommended.

Yeah, my ph like A frames and TSX. I bought several hundred .375 fail safes long ago when they quit making them. My RUM shoots them very well. I’m going to load them or the TSX, A frame or partitions in my dads Ruger 375 I just picked up. Which ever shoots best. Still researching the factory 375 Ruger ammo too though.

I have used the 270 TSX on 5 and each was taken with a single shot. Used the 300 AF on one but needed 4 shots. At Ruger velocities I would use the 270 TSX. Buffalo are usually in herds and the TSX 300’s tend to full penetrate, not good.

The DGX will probably work, they just aren't in the same league as the TSX and A-Frame. The Barnes and Swifts pretty well set the bar for expanding bullets and they both have a fine reputation in Africa. Which is a little odd since they are very different bullets.

The FailSafes are good too, they just were abandoned too soon by Nosler and Olin.

Tell us more about the Model 70 375 RUM. Putting one together for myself for a possible lion hunt. Have you used it yet?

It started out as a m70 CRF 338 win mag. I’m guessing I bought it new about 20 years ago. Never even shot it as I have an old 700KS 338. Anyway had a local ( Memphis tn) smith screw on a 26” fairly stout Douglas barrel and put a set of NEF express sites on it. Factory stock. Never bedded it or anything. Just opened up the barrel channel a bit. I think I did some work on the follower spring and mag box to get it to hold three in the mag. It shoots wonderfully. 300 grr partitions, the old 270 spire point and 300 RN Hornady’s always shot very well. Never tried any x or TTSX but it also shoots the 300FS into small groups too. It’s got Talley mounts and a 1.5-5 Leupold scope. I did put a 1” decelerator pad on it. It is pretty lively when you shoot it.... if I were to do it again I’d probably go 24” on the barrel. It’s a pretty long rifle. But I wanted all the RUM had to offer.

Go with the 300 gr partitions. They're what I use in my FN/Sako 375 Wby. I also like a 300gr solid on down in the magazine.

I used 300 grain Nolser Partitions out of my 375 Ruger LH. On my 1st bull it was a quartering to shot @ 50 yards. One shot inside the front shoulder----thru the heart & lungs. He went about 50 yards & piled up. The 2nd bull was a high shoulder shot. It broke the shoulder & took out the top of the lungs. He required a little tracking & a follow up shot. I used Win Mag primers, 81 grains of IMR 4350 & a 300 grain Nolser Partition.

Did you find that LH 375 Ruger? Mine is a Hawkeye.

I would start with a Barnes 300gr TSX, 270gr TSX, then an A-Frame. Whichever shoots best in your rifle.

Can't go wrong with TSXs, as others have said. If I was on a plane tomorrow with my .416 Rigby, that's what I would have packed.

Every time a PH asks what bullet I’m using, I reply A-frame. They just smile. They simply work. Next question?

When I asked my PH in Zambia what bullet he preferred in a 404Jeffery for Buffalo.

He stated "TSX or A-Frame, whatever shoots best"

TSX shot best, and worked perfectly on a buffalo.

I had great results with the Swift A-Frame. That said, while I have not used it personally, I have also heard good things about the new DGX Bonded bullet as well.

Thx. I bought some 270TSX for my dads 375 Ruger with the 20” barrel. It’s shooting .5” three shot groups at 100 yards with a book max of RL15. I’m guessing 2600 FPS or so but I haven’t chronographed it. I chose it over the 300 because X’s “thrive” on velocity and out of that short barrel I wanted to try to get as much as I could. We should be hunting herds so I was also scared of having the 300 grainer shooting clear through. I did finally get in tough with Bill from Swift bullets but by then I had a 1/2” load using the 270TS. My RUM is shooting them at about .7” and groups are getting tighter as the powder charges go up, but so is the recoil. I think my last load was 96gr of H4350 and I think the max is 98...but it was a lot nicer to shoot at 92.... if a 270TSX @2750 won’t kill u buff I doubt an extra 100fps will matter. FWIW the TSX are quite a bit more accurate than the 300 A frame factory loads out of my rifle.

Saeed on the accurate reloading forum has a favorite 375 x 404 Jeffrey which is practically the same as the 375 RUM he has shot several hundred buffalo with Barnes Bullets, he has used others, Swift, Rhino and more but keeps going back to the Barnes.

I have used the 400 gr. SAF twice in my 404 Jeffery on Buffalo in Zambia with success.

I am now using the North Fork 430 gr. softs in my 404.

270 gr. tsx's worked very well for me on Buff.

Tejano, Saeed turns his own Bullets. He coats them with Moly. They are called Walter Hogs.

Both rifles should have the same safeties, etc so there is no confusion in a stressful moment; i.e, two Winchester model 70's' etc.

Barnes TSX, Barnes Banded Solid and/or Swift A-Frame Both softs and solids should feed, extract and eject perfectly. Both softs and solids should shoot to the same point of aim. if cat hunting, Nosler Partition.

The foregoing is based on personal experience.

I used a 300 grain TSX at 2830 fps from my .375 RUM on my Zimbabwe buffalo. Perfect mushroom, found it in the off shoulder.
