Just a PSA, they're not suitable for larger animals.

The .284" 150 gr BTHPs are reasonably accurate, I had loaded a bunch for range use in my integrally suppressed 7mm-08, and they're what I had on hand when a small group of mulies showed up behind the shop Friday afternoon. I put the crosshairs on a larger one that was quartering slightly at about 120 yards and scored a solid hit. These loads are doing about 2,550 FPS muzzle from the shorter barrel of the integral, but is was still explosive.

Worked out OK for medium game, but I think penetration would have been a big problem with a larger critter, even a smaller cow elk, especially if it hit something more substantial than a rib on entry. On this maybe 200 lb animal, the bullet clipped a rib and only hit lung inside, still opened up enough to create a nearly tennis ball sized exit wound.
 
I would call that a good bullet. But I don't shoot elk either.
I couldn't see it failing to kill even if it hit a shoulder. The exit might not be there. But the lungs would be destroyed.
 
Technically they are known as open tip bullets. It is simply part of the manufacturing process and isn't necessarily meant to cause bullet expansion. In fact most of the time they don't expand more than conventional bullets.

Some bullets such as this Lapua Scenar leave a rather large empty space in the front of the bullet. This allows for a longer bullet with a higher BC, but at a relatively lower bullet weight. A 155 gr 30 caliber Scenar will be about the same overall length as a conventional 180 gr bullet. This gives the shooter the velocity of a 155 gr bullet, but with the BC of a 180. And they have proven very effective on game.

Most of the plastic tipped hunting bullets are really no different than the same bullet with a lead tip. But the plastic doesn't get dinged up and out of shape as easily as one with a lead tip.

Here are some other examples. Note how the tip of the Ballistic tip and the Partition are similar, but the Ballistic Tip is less deformed. Also note that the 155 gr Scenar is longer than the 175 gr Match King.

I killed many deer with the .257" Hollow points in my .25/06 ....

The Sierra 120 grain HPBT which was designed similar to the Lapua 155 grain ...they are no longer made ...

The Hornady 120 grain HP ... was a flat base bullet ....similar design ...no longer made either ...

The Sierra was a more "tough" bullet compared to the Hornady ...but both would smack deer ...
 
The critical thing to note is the thickness of the jackets!
On the left three premium HUNTING bullets, the bases of the jackets are thick and tapered.
This controls the expansion and being bonded or partitioned prevents the jacket and core from separating.

The “MATCH” bullets have exceedingly thin jackets. The Sierra especially is noted for either failing to expand or violently breaking up. No in between...

The Discontinued Sierra 120gr GameKing was NOT A MATCH BULLET! It had a thick tapered jacket that controlled expansion and enhanced penetration. I killed a number of deer with them in both.257Roberts and .257Wbymag. My best friend just today told me he had three boxes of the 5he bought in 1982 when he bought his Interarms MkX in .25-06. I’ve seen him shoot three-touching at 100yds checking zero! 43.0gr of IMR4320 for only 2,800fps. He was surprised that my .257Roberts gave similar speed with H4831!
I’ve still got a box of them too!
Yeah! They do “smack” deer!
But they don’t have big B.C. Numbers.
