[QUOTEWhat is the difference between the TSX and the original X from 25 years ago or whenever ? ]
The big differnce in my opinion is barnes owned up to the fact that the first generation bullets werent reliable.[/QUOTE]
Uhmm actually that^^^ is subject to some factual modification.
There are significant differences between the Barnes X and the TSX. The main issue with the older Barnes bullets was that they copper fouled your bore really bad.
The TSX is not nearly as bad in regards to bore fouling due to the fact that a TSX is a modified bore rider bullet IE the shank of the bullets is under caliber and the bullet actually rides down the bore on the bands that have been machined into the bullet. Which reduces the surface contact on the bullet and greatly reduces fouling issues, and chamber pressure.
The TSX also has a different nose cavity configuration. The nose is staged and scored so that it opens up much faster than an old Barnes X. The very tip of a TSX is paper thin and it tappers and gets thicker towards the shank. the scoring at the tip is in place to ensure violent expansion at contact and of course the bullets tappers so that it will retain maximum weight for penetration.
What the TSX lost to the original Barnes was B.C. the TSX is a less slippery configuration that original Barnes X.
I've also killed hunderds of head of game with old original Barnes X Including feral hogs primarily and deer, elk, antelope, coyotes, wildebeest, springbok, kudu, blessbok, warthogs, zebra,cape buffalo, elephant and other assorted sundry African and American critters. I've never had any issues with them opening up either.
What I did find with the original Barnes is that they simply would not shoot well not of some rifles. I have
personally never seen a rifle that would shoot the dog snot out a TSX. Well I take that back I did see one but it was a .270 WSM that hadn't been cleaned in about 500 rounds. After a serious cleaning session and a major copper ****** in the bore it magically started shooting very tight groups again.
Now am I saying the TSX is a perfect bullet that is 100% fail safe? Of course not nothing is. I've seen some spectacular failures in just about every make and model of bullet out there. I've seen a Accubond out of a .338 RUM come completely uncorked and blow to tiny little bits after only about 4 inches of penetration. I saw a 165 gr Corelokt out of a .308 win blow itself inside out on a feral hogs shoulder and stop cold in ther meat never even breaking a bone. A couple of cowboys roped that hog three days later and cut his throat with a knife we dug the failed Corelokt out later that day.I've seen all kinds of failures in bullets over the years and the reason I know they were failures is that we pulled them out of dead animals. Most had been killed with a a second or third shot or found later which is why I can conclusively say that such and such bullet failed in such and such way as I have it in my hands and am looking at it. The ones that got away due to bullet failure remain the questionable category because you don't really know where you hit the animal until he's on the ground.
I can't tell you how many claimed perfect shot I've tracked over the years only to find that that "Perfect right behind the shoulder when it broke" shot wasn't even close to being perfect or anywhere near the shoulder. Me and my dogs dogs tracked a scant blood trail on a hog for two days on one of those deals that turned out that the perfect shoulder shot was actually through the top of the nose just forward of the eyes. he kept dribbling blood and we finally put him down after nearly 48 hours. When the dogs can't catch something that's bleeding something is not right!
So while the Barnes is not a perfect bullet none are, what the Barnes TSX is, is a very very reliable tough bullet. And probably not the perfect choice for really light thin skinned stuff like deer. I really like the Accubond on big deer. They act very much like a non nose deforming Nosler Partition. And yes I've seen one fail. So what, for the most part they are fantastic!
