R.I.P. Ammo – Fad or Functional?

The firearms community recently has been buzzing with discussion about G2 Research’s new 9mm round marketed for self defense: R.I.P. Ammo.

Even before getting the round to the range, the R.I.P. projectile makes quite a first impression. This lead-free hollow point is made completely of copper. Each projectile is precisely CNC machined to get its fierce-looking cuspidated rim. The 96 grain bullet is designed so that, on impact, each of its eight points separates from tip to base, petalling within the wound channel. Petalling projectiles isn’t a new idea, but the R.I.P. round takes it to a new level. As you can imagine from self-defense ammo that requires CNC machining, R.I.P. 9mm isn’t cheap I’ve seen it selling for about $45 for a box of 20. Even so, it has been selling out at stores since its release.

According to their website, one of G2 Research’s goals with this ammunition was to engineer different projectile behavior through varying substances. The end result is that when the R.I.P. bullet travels through a [largely] fluid substance, such as within the body cavity, the “petals” fragment, breaking from the original projectile, creating additional, smaller wound channels. In this situation, each petal’s trocar, that is, three-sided or triangular, tip is geometrically optimized to move through gel or liquid (with little resistance), allowing the petals to travel away from the path of entrance at nearly 180º. Both the angle of travel, and the reduced friction of the projectile shape serve to enlarge the potential injury size, maximizing damage.

This same projectile, however, behaves differently through more solid mediums. G2 Research likens the R.I.P. round’s function when shot through plywood to that of a hole saw. The sharp tip drives through the wood, and the hollow fills with the material. The more solid projectile conserves more energy passing through the plywood than would a standard hollow-tipped projectile. However, this has given rise to some concerns of over-penetration, especially for those considering the R.I.P. ammo for home defense. Richard Ryan captured slow motion footage of just that scenario. If you haven’t already, check out the above video to watch his ballistics gel tests.

What do you think of the new R.I.P. round?

    Remember the Aguila IQ? Pretty much the same thing… Would it kill a badguy? Probably so, but so will FMJ with well practiced shot placement. Moreover, this is no magic bullet that could make up for poor shot placement, even if it causes faster blood loss… thats not what stops people in the noment.

    There is another new ammo, it splits into 3 and is tethered together with ballistic cord and goes to a diameter of 15″.

  • EricKmiecik

    Looks very impressive. But,ballistic gelatin is very different from a human body.  It’s impossible to know if this ammo will be more efficient than a old fashion JHP. Or something also exotic, like a Glazer Safety Slug.

  • drmorris9

    By their own numbers, it preforms very similarly to other fragmenting, high velocity rounds on the market (they have been around since at least ’75).  There is a reason this type of round has not been adopted by professionals on any significant scale.  The marketing style and hype will probably sell some ammo initially, but then as more tests and numbers come in, people will realize they are no better then the other high velocity fragmenting rounds they don’t buy.

    I’d be willing to bet it is a very lethal round… unfortunately the “nicks” in major organs will cause a slow death so the attacker will have plenty of time to kill your or your family before retiring for the evening and dying at home.

  • RonLarimer

    EricKmiecik  That is not ballistic gelatin. It appears to be clear Jello.

  • I suggested at the RatedRR video to see what it would look like going through a rack of ribs and then hitting the gel.

    The way I do it currently, is practice with FMJ ball ammo, but carry JHP that I’ve run enough through the firearm to know it generally won’t jam/malf.

  • EricKmiecik

    RonLarimer EricKmiecikYes. But there’s any difference in the composition?

  • RonLarimer


  • EricKmiecik

    I see. But don’t still don’t represent well a human body.

  • JunkfoodZombie

    Another in a long line of novelty rounds. The only reason I would buy some would be for the future so I can say “remember when?”

  • RonLarimer EricKmiecikThe ballistics gel that Richard uses is Clear Ballistics. Their motto is “See what you shoot.” If you like, you can check out their site here:

  • EddieMickle I would like to try it out myself… but I do like the slo mo angle Richard Ryan’s vids offer.

  • peter3101 Oooh, I haven’t seen that. What’s it called?

  • drmorris9 Thanks for sharing your input on the subject.

  • Jim P. That would make for an interesting watch, for sure–for me, at least. :]

  • JunkfoodZombie It sure looks flashy, no? lol

  • RonLarimer Defending my life with lethal force is something that I hope I never have to do.

  • JunkfoodZombie

    Oh, the machining is beautiful and it’s probably the coolest looking bullet I’ve ever seen. It’s just too light. Penetration in gel is not the same as hitting bone. Deady? Sure. More effective than an HST or Gold Dot? Hardly.

  • The reason I would like to see it is from the duplication of shooting center of mass and then you hit a rib or sternum and then going into the heart/lung/liver.
    The drywall doesn’t seem to have the same density as bone, but a cinder block (a different video) doesn’t seem right either.
    I definitely am not going to pay $2.25 per round unless it has a track record that it is a “man stopper”without over penetration. JHP has the same risks.

  • Fiero11

    FateofDestinee peter3101 It’s called T3 by Advanced Ballistics Concepts (ABC). I think it is still being tested and is not yet on sale publicly, but I am looking forward to trying some out and keeping the lethal rounds on hand. They state they are developing non-lethal, incapacitating , and full lethal rounds. I am looking forward to seeing some further tests and results.

  • TonyFrank1

    Doesn’t matter to me, I always shoot for the Head #headshotsonly

  • drmorris9

    FateofDestinee drmorris9  Thanks for providing a great forum where I can do so.  I didn’t actually intend to sound so negative.  I am glad people try new things and innovate, but the marketing on this one is a little over the top and borders on deceptive (using joules instead of Ft/lbs, using smaller then normal gel blocks for a more impressive visual, whatever that ballon thing is, etc.)  Richards video is awesome.

  • JimmyOgletree

    I might get a box because I love engineering, but that would be the only reason, ill stick with my standard JHP ammo

  • Barnes

    Personally, not a fan of it. I was however just going to buy a box just for novelty sake. But its a little too expensive for my blood for a novelty.

  • hartcreek

    At least this video is a better representation.  I was very critical of the manufacture’s website video using full automatics and they turned the blocks sideways for some shots and used way to many hits so that you could not really see what happens with one projectile.  I really do not see this selling to  serious shooters as what we already shoot is deadly.  I would however like to see what this round would do on soft body armor.

  • ThorDeSchane

    Pass. Too gimmicky. Feel free to try to prove me wrong, though.

    As I said on FB a few minutes ago, If they tested it against an Animal Carcass, particularly the sternum or breast plate, it would perform horribly, even more so if it had 6 layers of denim over it. A Gel Block simulates flesh, but it is nowhere near animal flesh, and considering humans react differently than a gel block, I would wager it would leave a 1 in diameter cavity under the surface of the entrance wound if it opened (from the fragments, and they would probably stay near the surface due to the extremely low grain weight of each trocar) , and the base would penetrate 4 or 5 inches. An easy GSW to repair. It’d be like a .22/25, with a couple of little fragments stuck near the entrance.  The only way I could see it being effective would be to pull the projectile, load it into a .380 casing, and then use it as a pocket rocket “Gut shot” pistol. That would probably leave several minor intestinal lacerations and cause Sepsis (Fecal I.V) It just doesn’t compare to what a Copper Coated Lead HP out of any pistol can do.  If you want a hard hitting self-defense round for a 9mm, a 124 Gr +P+ Federal 9BPLE load is a BAMF. I personally like 147 Gr +P JHP, and Hornady’s 135 Gr +P Critical Duty. Also remember, at 44 dollars a box, it would be very expensive to train with (Which you should train/test function your carry load in your carry pistol) If you can’t train with it, at least enough to see how it functions in your pistol. I recommend 100 rounds minimum, which equates to about 225 bucks for that load. I am not an expert, but not many of us can afford that. You can buy a box of Hornady Critical Duty 135 Gr +P at 35 for 50 rounds, so 70 for 100.

    By Gut Shot pistol, I am referring to when Gentlemen and ladies back in the day carried Vest Pocket pistols, Derringers, and derringer clones. Like in the early 1900s, a .25 Auto Browning Pocket pistol would be carried in the vest pocket of a gentleman’s waistcoat, and if robbed or insulted he would empty it into the aggressor’s abdomen. (that is where the phrase (A .22 or .25 is most likely to kill you….tomorrow). It was a painful and agonizing way to go. It was a popular technique and fashion in Europe in the Early 1900s as well, with the .25 and .32 ACP pistols becoming as common as a pocket watch. Off topic, I still really want a Beretta 950 BS. 🙁 A Man should have a nice wallet, pocket watch, Pocket pistol, and a pocket knife. I’m missing the pocket pistol. 🙁 Of course the pistol would be a backup to my backup. I just want to have that connection to my ancestor’s. My Grandpa carried a Beretta tip up .25 in his back pocket till the day he died, my Grandma still bears a projectile in her bicep from an incident involving him trying to shoot his broken leg.  Sorry about getting off-topic, I had to go with it…Retrograde and all. 🙂

    Fiero11 FateofDestineepeter3101Is that the shotgun round that Tom was trying to sell…err, I mean review about a month ago on Weapons Education?

  • JoeFabeetz

    Fiero11 FateofDestineepeter3101I see Peter (below) posted a link to Toms vid about that round.  I could have sworn this was a shotgun round when Tom first presented it.  Hmmm…Guess I wasn’t paying enough attention.

  • Fiero11

    JoeFabeetz Fiero11FateofDestineepeter3101 You might be right that it was primarily a shotgun round, but things always have a way of progressing into other caliber development if successful.

  • AlessioBaldi

    The idea is excellent, but I’d like to see how it performs passing through bones and/or winter clothes. My fear is that the bullet either fills with material (fabric/bone tissue) and does’t open, or the 8 points separate in the clothes/bones and lose there all their energy. Another concern is feeding reliability, with that serrated edge…

  • EricKmiecik

    In the end, we going to comeback to our old fashion bullet designs and this bullet will end as a fairy tale.

  • PaulDragotto

    your better off with mag safe bullets. this round i would like to see tested on a side of beef, with denim clothing and a jacket. i bet it would break apart before it enters the flesh, or just clog up. one ass hole was selling a box for $75.00 on gun brokers and some fool bought it.  big gimic. your better off with a pre fragmented copper jacket hollow point+p+.

  • pilotaaron

    I think it is a crappy round. The trocars hardly penetrate 4-6 of ballistic gel… I’ll give it to their marketing department!!! Anyone would be better served by a real round like Federal HST, Gold Dot, PDX1, etc…

  • PaulDragotto

    another 21st century bullet. your better off with “mag Safe” ammo. it has steel shot and is in a copper jacket filled with Aircraft epoxy. they won’t clog up with clothing and do the same thing the rip does. sell only 6 rounds, but cheaper than the price for 20 of the RIP. I would like to see a test on a side of beef (not frozen) with denim clothing , or a jacket . i bet it will clog up. my opion. BIG HYPE!!

  • John Ritenour

    IMHO – I think buying a good quality JHP ammo and training with it is the best solution. I concede that some of these specialty/boutique brands do indeed have better terminal performance. But their high price and limited availability make it expensive and difficult to become proficient in their use. A case in point is the 9MM RIP (Rest in Piece) round. The average retail price is $45.00 per 20. As someone pointed out, that is $225.00 per 100 rounds. Checking on the Internet, I found a 500 round box of Remington 9mm 115 grain JHP for $211.00 inclusive of shipping. That is roughly a 5 to 1 price difference. An additional bonus of purchasing the Remington Ammo is that I will also have enough pocket change to order an overpriced cappuccino at Starbucks. In closing,
