A standard load for the 338 win mag is with the classic big game killer load of a 250 grain nosler partition @ 2660 fps

Knowing what I do about how a NP and a TSX work, I am surmising that a 338 210TSX @ 2625fps would do the same job.

Note we are not talking about "stopping" a grizzly or elephant in full charge, where the heavier bullet may (or may not) have the advantage.

My theory is that about 30-40% ( about 80-90gr) of the partition is blown off at initial impact. (as designed to do) This creates a large initial wound cavity, and it is followed up by the deep penetration of the remaining 60-70% (about 150gr)

So a 210 TSX that expands fully, yet retains most of it's weight woudl still offer the same advantages in penetration and since it is fully expanded larger than what is left of the NP shank "mushroom" they should do similar jobs.

I will try to rope bartell to do some newspaper penetration tests...
 
You know what, Gatehouse? I wouldn't be surprised if the TSX actually outperformed the Partition.

While you're at it, I'd recommend you try a 140-grain TSX in 7mm, at 2,800 (out of a 7-08 or 7x57) along side a 160-grain Partition at, say, 2,550. Next, try a 168-grain TSX at 2,850 out of a .30-06 along side a 200-grain Partition at 2,600.

My money says the lighter TSXs will perform and penetrate virtually identically, and will surpass the performance of the heavier Partitions.

What do you think?
 
This are both ideas I would hesitate to bet against. I had the 210's moving out of my .338 at 3000ish, and I would guarantee it would end to end a moose no problem.
I would like to see a practical test.
 
Could some limited fragmentation be beneficial in increasing the wound channel? Just a thought.

Yep, exactly John Nosler's thoughts behind the construction of the Partition. The front part fragging increases the size of the permanent wound channel.
 
tsx ?

Do you have actual examples of a 210 expanding and penetrating through a moose front to back ( or back to front)?

A little different but my 7mm RM with a 160gr XLC @ 3000fps had slightly better penetration than a 285gr GS @ 2700fps out of my .375 H&H, both at 90 yards.
 
I believe that I agree with what you are saying Gates. To my mind the TSX is "the equilizer" it seems to give heavy bullet performance from lighter bullets. I figure the TSX really expands the role of plain jane cartridges making them much more versatile.
 
oh yes, I recall the bullet tubes, I think. lil devices that have sensors to measure bullet dynamics. how would wet or dry paper tell you about the bullet tho? paper has little to no resistance in comparison I would think (my thinking is obviously wrong :rolleyes: ) so how can you tell 'penetration' with it?
 
You stack wet phone books on their ends and keep stacking them until they are about 40 or more inches deep. This will simulate going through an animal somewhat (kind of similar densities) and since it rarely goes all the way through all the phone books , you can retrieve your bullet and see what kind of fragmentation occured. The mushrooming will be evident, and you can see if the bullet broke apart into pieces. The bullet can be weighed to see weight retention. Often with a bullet such as the TSX if often passes right through an animal so it is hard to assess if it mushroomed correctly (with the petals folding back) . Occasionally, some or all of the petals break off and without a "larger frontal surface area" it has too little resistance to stay within the animal.

You probbaly need more than one sheet of paper;)
 
I would agree with the original post. I was shooting 130gr TSX at 3400fps out of a 300wsm for deer and shot a 1 1/2 old buck through both front shoulders and and took the spine out also with complete penetration at 457 yds (laser rangefinder). That bullet would only be traveling about 1900 fps at that range and only has a sectional density of .196.

The 210gr TSX for the 338 has a sectional density of .263 and would be traveling at close to 2200fps at 200 yds if it left the muzzle at 2600 fps. I would think you should have awesome penetration with that setup. Certainly more than enough for any moose or elk you may encounter.

I am ordering some 130gr TTSX for my 300WSM for a sheep hunt. Currently I use 168 or 180gr TSX, but I like the idea of a 3400=3500 fps load:D

You shot anythig bigger with them?

What powder are you using?

Snoop around the Barnes website gates, I think this is the bullet/cartridge combo Conni Brooks has settled on. I am unsure of the loading tho
