I bought a box of the SIM-X hollow points and a box of the range ammo. Mainly out of curiosity. Weight reduction and concealment have been my obsession for years. I'm also equally interested in non-lead projectiles. Solid copper, composites such as ARX and hollow copper like Sim-X. This ammo is substantially lighter than its leaded contemporaries.

I was shooting four inch groups at 15 yards, rapid fire with my trusty Hellcat. I didnt check the makers claim of velocity because I didn't feel like setting up the chrono. I'm too lazy to make a science project out of it. My measure of a defensive/carry handgun and ammo is really quite simple. If I can put 5 rounds off the draw rapid fire inside an 6 inch paper plate at 15 yards, it's good enuf.

My Hellcat is trusted and consistent from an accuracy standpoint. I must say that this SIM-X ammo definitely takes some of the inherent snappiness out of the typical 9mm round. Muzzle flip was noticeably less. I noticed no difference between the hollow points and the range ammo. I must admit that now I am curious about the claim that it is as fast as +p. I may have to set up the chrono. Wish I had the new Garmin.

I've never seen this brand on the shelf. Someone recommended it to me so I bought a couple boxes direct thru their web site. The web site requires you to order 100 rounds. I asked via email if they would sell me two boxes (20 rounds each) to try it out and they did. It's pricey at $1.30 per round, so you wouldn't want to burn thru 200 rounds of this ammo on range day. But as a defensive round, it checks all the boxes for low recoil.

I'd like to see some ballistic gel tests to validate their velocity claims and thus penetration. Expansion as well on the HPs.

Never heard of 'em.

I wonder what the expansion is like in ballistic gel.

I don't put a lot of faith in YouTubers proficiency in ballistic testing. A lot of these monkeys have no real expertise in this discipline and make their own gel, which is not really FBI quality ballistic gel.

Even so, this vid seems to suggest velocity is overstated and penetration of the SIM-X is not great. There's another vid conducted by a dude who quite obviously pretends he's a woman and he-she's results were similar.

Expansion was fine. Nasty wound channel for sure. The issue is penetration, which was only about 6 inches.

I'm often saying, "there are no laws like the laws of physics," which I know as someone with an engineering degree, you know very well! Even at the stated velocity on the box, it isn't hard to imagine how a 9mm HP projectile of a mere 45 grains is going to decelerate rapidly and isn't going to penetrate far in any kind of gel or body tissue. A "mere 6 inches" isn't going to reach vital organs, unless they take the rounds to the face or neck!
 
What's new in the world of physics? Nothing! :)

The one unknown here is whether the ballistic gel was the right density or not. I think it's reasonable to assume, however, that this ammo isn't on par with more traditional hollow points or even solid copper. Even if the wankers on Youtube got the gel wrong, they would probably not be that far off.

12-18 inches penetration is the FBI standard as we know. The more popular defensive ammo in most cases exceed that standard. So the ruling on this expensive ammo? Eso no es bueno. Glad I didn't buy 100 rounds.

That old momentum formula raises its ugly head.

p=mv
 
I wonder what barrel length the maker used when they stated their velocity numbers. The two YouBoob testers did use a short barrel firearm. Even so, a short barrel is to be expected in a defensive handgun.
 
Liberty didnt do much better.

Best to save some dough and go with Golden Sabre or Winchester Ranger or Defender, Federal HST or Hydra Shok, which are often on sale someplace. Underwood if you really gotta have premium.

A while back I bought what would amount to a lifetime supply of defensive HPs... Federal HST, Winchester Ranger SXT and T-series. I think I may have some Gold Dots, too. Can't go wrong with any of those.

Yup! Got some Gold Dots!

Yup, I prefer ammo commonly issued by LEAs to their LEOs. That should take any questions in court after a Defensive encounter about the ammo carried in my EDCs off the table, . . .
Prosecutor: "Why did you load XYZ ammunition in your firearm?"
Me, "Because that's the ammunition my county's sheriff's department issues to their deputy's! Next question!"
 
This is rather off-topic from the SIM-X ammunition. I however am curious to know if ya'll have heard of Halo Ammunition and what your thoughts about it are? They currently only make 9mm, I've been tempted to buy a couple and try them out because from the videos I've seen and their website, they talk a rather big game about being the best 9MM Self Defense rounds on the market. I have not heard a lot from the other side of the sales table though.

Personally, I shy away from what I'd call "boutique" defensive ammo. I'm sticking with the big players like CCI, Federal, Winchester.

Can't recall ever hearing about Halo. It looks a lot like RIP G2 ammo. This kind of projectile is referred to as a trocar design, whereby on impact the bullet splits into separate pieces (trocars) that supposedly shred the bejeezus out of whatever you shoot... creating a nasty wound.

The problem with this design is penetration. 4-6 inches. Boutique ammo companies have been playing around with these shredding bullets a long time. They have overall proven ineffective. It's impressive to observe someone shoot this kind of ammo into a watermelon and see it literally explode. Cool, but not the same as a human or animal that has hide, muscle, organs, and bone inside. Bottom line is they have been proven over and over to not be more effective in stopping a threat than traditional defensive ammo. It's a novelty. Newbs think it's cool and that's understandable. It's scary looking.

Not to seem callous, but there's only two ways to stop a bad guy. 1.) Cause significant, rapid bleeding by hitting a vital organ or artery; or, 2.) Stop the heart or cease neurological function by damaging the brain. Both are incapacitating. Anything else... it takes about six minutes for someone to bleed out - if you get lucky and hit an artery in the extremities. That's enough time for them to kill or injure you before they drop. All those vital body parts are surrounded by clothes, skin, fat, muscle and surrounded by bone. In short, shot placement and penetration is paramount. Stick with traditional hollow points that expand or solid copper 'spinners' that use hydraulic pressure to create a large wound channel.

For hunting, I wouldn't dare shoot a hog with this kind ammo because all it's going to do is piss him off. :) When hog hunting I put a 10mm hollow point in its head when I approach - after shooting it with my AR10 (308). Sometimes they get up and are in a bad mood after you shoot them the first time.

For big game, such as elk, high velocity solid copper rifle rounds have become popular.

I can agree on that. I was unfamiliar with the design! Noob life is my life! I mostly always use Federal, or Hornaday(which I would consider a bit boutique-ish) cause my local shop seems to really only carry them, and like two other brands who I’m not always a fan of branching out of my comfort zone for. I saw Halo in a magazine and looked them up. I was definitely liking them because of the design. Reminded me of some sort of medieval weapon by modern means, lol. In terms of practical application they seemed rather sketchy. My CCW instructor also talked about carrying chest seals and a trauma kit in the event that administering some trauma aid can play really nicely in court and I also don’t really want more mental weight to carry if I can at least keep my attacker sustained till EMS arrives. Seems weird for some folks I know but I don’t want to be the reason someone is dead if I could have prevented it. I’d like to know that I did at least what I could to help even if the POS was threatening my life. I can’t justify spending the money they are asking though. Rather get some tannerite and a watermelon to see it go boom, probably cheaper too! Still though, part of me still does want to see that watermelon explode just with a 9mm😂 young, dumb and foolish with funds in pursuit of fun! I appreciate y’all’s input! Sorry to have hijacked Bongo!

This precisely. . .because ammo such as you list above has already proven effective SD ammunition by law enforcement use "on the streets!"
