In terms of damage, the TSX

In terms of damage, the TSX is up to the job.  Here's a pic of me skinning out a brownie...that's an entrance wound where the TSX entered the ribs after going through the shoulder.

I shot this brown bear at 13

I shot this brown bear at 13 yards with a 300g A-Frame out of a Rem XCR II in 375 Weatherby. The bear was quartering towards me. The bullet took him through the right front shoulder and traversed the bear diagonally passing through the left rear thigh and ending up under the skin on the far side of the left rear leg. It still weighed 299.5 grains! I shoot the 570g TSX out of my 500 Jeffery at 2300 fps. I'm sure it's a great cape buffalo bullet, but am hunting thin skinned game (elk) this year with it to convince myself it will open up easily enough should I ever take it brown bear hunting. If not, I have some 570g A-Frames I can develop a load for.

Barnes vs NP bullets

[quote=Tndeerhunter]..Now, I've been curious about the fairly new phenomena of getting high weight retention and just why that is...Of course, fast forward some 50 yrs and the Barnes X is all the rage because it penetrates and ALSO retains 90+% of its original weight. Now it does not mushroom as large as a NP but, by golly it maintains all that weight.[quote]

My experience is that Barnes TSX and TTSX bullets expand to a greater width than Nosler Partition bullets.

I've shot 20+ elk and moose with .30 caliber 180 gr Nolser Partition bullets at .300 Win mag velocities. I have never spent a lot of time digging through an animal to find my bullets, but I did recover many of those NPs just under the animal’s skin on the off side.

Every partition that I have recovered had completely shed its front half, and the largest mushroom had opened up to a 0.50" diameter.

Since I built my .300 Weatherby five years ago, I have used it on several western hunts (including two bull elk), a South Africa plains game hunt, and a New Zealand hunt. I shot Barnes 168 gr TSX and TTSX bullets on these hunts. Most of the bullets either completely passed through the animals or I did not try to recover them. However, I did recover 3 of the 168 gr TTSX bullets (including one from a bull elk), and all three of them had mushroomed out to a 0.65" width.

I also recovered two 270 grain and one 300 grain Barnes TSX bullets shot from my .375 RUM into African animals, and all three of them opened up to 0.80" mushrooms.

The other animals that I shot with Barnes bullets that completely passed through the animals all had exit holes larger than the entrance holes, leading me to believe that the bullets mushroomed inside the animals.

And as to the question of why high bullet weight retention is important:

Tissue damage is a result of the energy from the bullet. The more energy that a bullet has, the greater it’s potential for tissue damage is.

A bullet's energy is a function of its weight and it's velocity. Reduce either the bullet's weight or velocity, and its energy will also be reduced. That’s simple physics.

As soon as a bullet hits animal tissue it rapidly loses its velocity and a corresponding amount of energy. If the bullet comes apart it also loses its weight, which further reduces its energy.

With equal velocities, a heavier bullet will have greater energy than a lighter bullet.

A bullet that comes apart too quickly may not penetrate deep enough to reach the vital organs of larger animals, and its energy will be dissipated in the outer muscle and bones of the animal. So a bullet that retains its weight will deliver more energy deep inside an animal.

375 H&H

I guess if I ever go grizzly or brown bear hunting, I would take my 375 H&H. Probably would load it down to around a 250gr to 275 gr bullet. I have all the confidence in the world in my 30-338 but I think I would want the big dog in my hand if I was looking through the scope at an animal that wants me for a snack! The bear in my pic was shot with my 30-338 but was a black bear at a measly 350lbs when compared to a griz. The shot on her was about 275 yards and she dropped with one double lung shot. I was still nervous about going down to find her after a 30 minute wait since she fell out of sight. So yeah, I would take the 375.

I've switched to the  Barnes TSX and TTSX in my three hunting rifles. 

I want bone breaking capability and penetration. No matter what I'm hunting I'll waste a little meat to get the animal if that's my only option. I've seen too many animals and people remain up and fighting, or running and hiding, with the traditional heart and lung shot. 

Just my  $0.02.

used a 338win/200gr Barnes x

used a 338win/200gr Barnes x on mine about 6years ago. If I was to go again? I wouldn't change a thing
