  Jfc I hope you’re not serious lol. These are self-defense rounds, meant to break apart inside the attacker or intruder, so you’re not shooting through walls, potentially killing people on the other side.

  Part of a defense training class includes, “know your target and what’s behind it” for a reason

    Nope, actually the opposite. They’re supposed to overpenetrate. But they look like they’re supposed to expand and fragment, right?

    Check it out: lehighdefense.com/…/xtreme-penetrator.html

    They do really cool stuff inside ballistics gel because of the surface pressure on that flattened tip

      You’re both wrong, they’re for unscrewing really tight screws.

      Yes, it generates a larger cavity/hole than a JHP (jacketed hollow point) and the article continues comparing JHP to this new round.

      A traditional HP is just that, the center is open, and it almost immediately breaks open on impact so shrapnel sort of goes all over the target. This is safer for everyone involved but might take several shots to stop someone because of the little actual penetration. Especially of a heavy canvas coat is worn out can severely degrade performance.

      This round, is copper filled with a fluid from the sounds of it, but instead of the front opening up in impact, this his there target and spreads from the rear (the fluid moving forward causing cavitation part). This means the round had a chance to penetrate while also expanding and puting pressure on surrounding tissue which causes more damage. Still though, as it expands, it should greatly reduce velocity and not go through the entire target. A JHP might go on 2-5 inches or more based on design and caliber. Maybe this could go 6-10 inches. If it did exit, there’s likely too little force to do extreme damage to whatever else it hits.

      I’ve got some in my safe, but never shot this particular round to experience it myself. I’ve shot all sorts of standard ball, FMJ, JHP, and composite or lead-free rounds of numerous caliber and form factor.

        Oh shit for real? I’m stupid and sent you the ones I’m not familiar with because I didn’t actually read it before sending. They also make them without fluid, just a solid bit of copper. Does the same thing but doesn’t expand

        I looked up “fluted penetrator” and just linked the first thing I saw, so thanks for the correction and actually reading the article that I was being too much of a tool to read.

        This is the bullet I should have used in the image and original comment.

      These aren’t really that effective compared to a hollow point. They create a big visual in ballistic gel, but in a more realistic medium they act more like an improved FMJ, but still over penetrate badly (which isn’t a good thing in most cases).

      They tend to be recommend as a bear round, where over-penetration is actually valuable and desired.

      The same manufacturer actually makes a deeper cut version that doesn’t over penetrate called the xtreme defender, which is generally still worse than a good hollow point in standard calibers, but can be a good option for weaker calibers like .380, where hollow point under-penetrate.

      however, for 9mm and above, you’re better off with a standard hollow point, which is more effective and far more affordable than the all-copper xtreme rounds.

        Oh, good to know. But how do you assess value? I know we like hp for transferring force but my personal attraction to these was exit wounds.

        Also according to a article I linked later, they break bones?

        Cool wasn’t looking for recommendations. You should have replied in thread.

  If the options are “Phillips head fucks shit up” and something not being fucked up by Phillips, assume the thing is about to get fucked.
