Looking through ammo, I found some Hornady hollow points that say XTP next to it, what does that mean?
What is an XTP designation?

Wish I knew too .. I guess an acronym which so far I can only guess at!! I do know tho ... when they are ''driven'' properly, expansion is excellent
Am using these now for my .454 and .44mag hunting loads.

They are Hornady's version of a controlled expansion bullet. Designed to function similarly to Gold Dots, HydraShok, etc.
XTP = Extreme Terminal Performance.

''Double Whammy'' there!!
That'll do for me ... thx guys! They sure are ''usefully'' extreme!

How does a hydra shok or XTP differ from a regular hollow point?

Oh and another question. 9mm hydra shoks come in 124gr or 147gr, what are the pros/cons of each? I imagine the 147gr would travel slower but the greater mass seems like it would be an advantage for personal defense.

UT ....... the way I look at it is the way they are designed to open their ''petals'' .. both of these have sorta inbuilt ''stress'' lines in the jacket . and so if hydraulic pressure in the hollow starts the expansion then the ''petals'' peel back a lot ... increasing effective cal by some large amount. More so and more uniformly probably than a ''std'' HP.
The HydraShok has that sorta inernal ''stud'' .... never quite sure what that does to be honest.
These and other similar offerings, seem to go for six ''petal'' peel-back.
~~~~~~~~~~~~~~~~~~~~~~~~~~
Oops near forgot ... those 2 9mm offerings from Federal ... I think there is some of the ''fast'n'light ..... vs ..... ''slow'n'heavy'' debate with those . I use the heavier ones for carry but to be honest have never done any comparisons.
Steve Camp tho may well have done.

The post in the Hydra-Shocks are suppose to direct the fluid volume to the sides of the cavity forcing the expansion faster than just settling in the bottom of the cavity first.
The 147 grainers are slower than the 124s, but they also penetrate deeper since they have greater mass. A 147 griner will also shoot to a higher POI than the faster 124 grainer.
Today there really aren't many regular hollowpoints. Just about every manufactor has their own custom high performance bullet designed to expand in adverse situations. They go by many names but they all serve the same purpose.

Hello. If interested, here are some observations concerning Hornady XTP ammunition.
http://www.hipowersandhandguns.com/HornadyXTP.htm
Since doing the testing for my book on 9mm Ammo and the Browning Hi Power, I have noted that with certain magazines I used, the factory XTP in 9mm is somewhat prone to set back if the same cartridge is cycled into the chamber from a fully-loaded magazine 5 times. Some other brands are as well and I believe that all will do it eventually, depending upon the angle at which the particular magazine directs the bullet to the feed ramp.
My main experience with the XTP line of bullets has been with handloads and I had not noticed the set back thing until trying some of the commercial ammo.
Best.

The XTP ammo is some serious stuff -- it's what I like best.
It penetrates a lot, which can be bad, but its results on media are often unbelievably explosive. Mr. Camp has a picture of a deer wound caused by a 9mm XTP, and it looks immeasurably worse than the several wounds in the deer my Dad's friend got a couple of years ago with a .30-'06, and a couple of shots from my .243.
I don't know what its effects would be in a self defense situation, but if it's good for hunting, why not for defense?

P.S. Whoops, looks like Mr. Camp beat me to the punch. Hey, my 500th post!

Hello, sir. Congratulations on your 500th! As I mentioned in the article about the wound, it is not normal an it is not what I've seen in any of the rest of the animals I've shot with the exact same load. I have no idea what caused its exaggerated size.

Stephen Camp's comments on that site match more or less every other report I've seen on the XTP.
Basically, it's a "deep punch" design. The JHP opens in a "delayed" fashion due to the unusual thickness of the jacket. It then doesn't open as "fat" as some other designs, such as most Cor-Bons and the Speer Gold Dot projectiles...but that lack of peak expansion translates as "deep punch".
The XTP 240 in 44Mag is a superb load for black bear, boar and deer, as it's a compromize between the deep expansion of a hardcast and the "splat" of a hollowpoint. It also makes a good modest-size deer or smallish boar load in 357, and it's a great choice for general woods carry.
But, it's not my first choice for street/CCW personal defense in urban/suburban areas (unless there's an actual bear threat) and I recommend avoiding it completely in calibers/barrels that are marginal in horsepower, such as the 380 and 38+P from a snubbie.
It does however have it's place, and when used for what it's good for it's among the best in the world.

Just a bit more data - -
I recall that when the XTP-HP bullets first became available, they were touted as performing well through a fairly wide, but well defined range of velocities. The Theory - - and it is said to prove out in tests - - is that a bullet strong enough to hold together and punch deeply needs a certain velocity to begin expanding. At the same time, if over driven, the same projectile will fragment and fail to penetrate properly.
I haven't loaded any XTPs in the past few years, but each box used to include a slip of paper saying something like, "these bullets are designed for proper expansion at velocities between 950 and 1220 FPS." The actual figures depended upon the caliber/weight/design of the particular bullet.
I thought this was an excellent way for Hornady to suggest most efficient use of their products.
I have never recovered an XTP bullet fired into tissue and so must rely on information from others. My only personal observation is that these bullets are quite accurate.
While the XTP-HP is the best-known and most popular series, Hornady also offers the XTP in a non-hollow point design. It is intended for SOME expansion at high velocities in larger, heavier, game. I never tried these, but understand they perform well within the specified parameters, and that they, too, are superbly accurate.
