Saw an ad in African Sporting Gazette for the new 350gr TSX in 375cal. That should be one long bullet! Wonder if there are going to be stability or powder capacity issues with the H&H? Is the Ruger the same twist as most H&H?

Can't find a 350 gr TSX (.375) on the Barnes website......does sound interesting

Are you positive it was a .375?? I've not seen mention of it and I get the monthly company newsletter.

It actually was not an ad but a press release. And yes, it announces a 350gr 375 Cal TSX. If it doesn't cause stability or powder capacity issues, it should be a real buffalo killer. In the RUM (or Saeed's 375/404) it should be devastating.

I see this as knee jerk pandering .... Is it going to expand wider than a 300 gr 375 TSX or the 270 gr TSX ........ Has any buffalo not died when shot with a 300 gr TSX ...........
.
.I doubt it will turn a 375 into a 416 , It won,t go as fast as a 350 gr in a 416 .....
.
. 375 Rum ,350 gr bullet @ 2550 , from a 26" barrel .
.416 Rem , or Ruger .20-22" barrel 350 gr bullet @ 2550 -2600 fps .. Burning less powder ........
.
. What Barnes should come out with is the 350 gr wt in .423 caliber ..........That would sure make the 4 naught 4 J alot more appealing ......
.
.
... If the bullet would consistently expand to 1/4- 1/2" greater diameter , then I could see it being a better killer . But then it may not be due to it,s much slower velocity ........and thats if it stabilizes ...

I can't imagine a likely application where this bullet would be superior to the 300gr TSX.

I can imagine some problems making this bullet work, especially in the H&H case where capacity is already a little on the low side with the heavier bullets.

Generally Barnes is know for recommending lighter weight and higher velocity for best results with the products they make. I agree wholeheartly that this is a change from the 'norm' for them. I can not see it outpreforming a 300 gain except in the case of perhaps a .378 weatherby or the like.

It's probably because Kevin Robertson has been pushing for heavier bullets for the 375. He thinks the standard 1 in 12" twist rate for 375 barrels "over stabilizes" 300 grain and lighter bullets. I'm no ballistic expert and have no basis for argueing one way or another, but another of his things is over penetration in buff heards. I don't think this heavier bullet will help that.

If the bullet is going slower, and expands more than the 300gr then it might be made to penetrate less.

Maybe apples and oranges here, but Gregor Woods in his book Safari Rifles, writes of a doctor who retired to hunt in Africa a lot. He did experiments shooting .22 cal. X bullets in both .22 Hornet and .22-250. He was able to dig out and examine most of the .22-250 bullets, but never from the Hornet, they were all through and through exits! It seems If you can expand the fingers out at 90 degrees and no further, that bullet penetrates like crazy.

I'd like to see a .250gr TTSX in .375.

Perfect for all larger north American game like grizzly, moose, elk. Shoudl shoot pretty flat,too .

True.
The greater sectional density will increase expansion rate and degree at any given velocity, even if the nose structure is the same.
It will be more likely to loose all its petals at a velocity where the 300-grainer might retain some.

When it blows off all its petals it may become a sub-300-grain, ragged-nosed tumbler, flip over and proceed bassackwards out the other side of the critter.

Where are the field test reports at various velocities from 2150 fps in .375 H&H (case capacity limitations) to 2850 fps in the .378 Weatherby?

Inquiring minds want to know.

Just curious.
Academic, don'tcherknow ... they should be as useful as ...

Long, soft , & slow ... back to the future I guess ... 318 WR geometry anyone ... ??

Just like prom night..... There was another thread someplace on AR discussing the 270 gr 375 as well. If the SD was high enough on the 350 gr bullet, it might be worth trying for close range work.

Uh oh! That is already getting some pinky fingers erect! SCHWING!

Like the original 8 x 50R Austrian boolits ... launching broom handle looking things at your target ..... Ja!! It's the 19th Century all over. Maybe it's supposed to be a SS pistol bullet ...??

Agree, it doesn't make much sense with a mono bullet, but a 350g Swift A-Frame in .375 caliber would be a sweet bullet in a 375 Wby Magnum, or 375 RUM.

Was this a premonition or what?

Actually North Fork came out with a 350g .375 caliber bullet in their excellent soft point line. Seems made to order for a 375 or 378 Weatherby.

This thread can be updated with the news that a 375 Tipped TSX 250 grain is now available from Barnes. That was the logical development all along. That will make for a near perfect 'plains-game' bullet that should be buffalo capable, though marginal.

The comparison with the new Barnes 416 Tipped TSX is interesting in its contrast. Instead of producing a 300 or 320 grain Tipped TSX, they have produced a 350 grain Tipped TSX in .416". This latter becomes a true 'all-purpose' plains game bullet that comfortably includes buffalo.

The equivalent in 416 for what they did in 375 would have been a .416 300 grain TTSX. That would have produced loads up to 3000fps in handloaded Rigbys, with the same SD as the 250 grain 375. But it but would have been marginal for buffalo.

A PS: on the note that Hornet were outpenetrating 22-250: my guess is that the Hornet bullets were so slow that they were not expanding and were penetrating like solids. All things could not have been equal because at some point the 22-250 would have slowed down to Hornet velocity and would then have penetrated 'like the Hornet', if both had the same expanded petal structure. Velocity is a friend of expanding 'X' bullets, it is win, win.
