Has anyone tried the new Hornady GMX yet, are they having similar accuracy and performance on animals as the TSX?

Thanks Bjarne

BaxterBI can see the handwriting on the wall and it ain;t looking too good for our friend Pb.

MileHighShooterWhat I want to know is, are these gilding metal bullets as strong as copper? It says they foul less, but Barnes addressed a lot of those problems in their new lines of TTSX, TSX and MRX bullets. Plus, lets see if they even offer them as components, or just as overpriced factory rounds.
If you think every possible niche has been filled already, thank a wildcatter!

Yes I'm sorry about it, but may admit that these TSX bullets are performing so well that Pb is about to be

KarooI am resurrecting this thread to find out if the jury has returned.
In theory they look quite good at a cheaper price.
What experiences?
04 September 2016, 03:36
SnellstromMy youngest son is shooting them in his .280, they are accurate in his rifle, just trying them out in my other sons .284 Win. Maybe we will have a report on the effects on Mule Deer, whitetails or Bear this year.

Mike_DettorreI have shot deer, pigs, and a cow elk with the 165 GMX out of my 308 win. Worked just fine.

Never under estimate the internet community's ability to reply to your post with their personal rant about their tangentially related, single occurrence issue.
What I have learned on AR, since 2001:
1. The proper answer to: Where is the best place in town to get a steak dinner? is…You should go to Mel's Diner and get the fried chicken.
2. Big game animals can tell the difference between .015 of an inch in diameter, 15 grains of bullet weight, and 150 fps.
3. There is a difference in the performance of two identical projectiles launched at the same velocity if they came from different cartridges.
4. While a double rifle is the perfect DGR, every 375HH bolt gun needs to be modified to carry at least 5 down.
5. While a floor plate and detachable box magazine both use a mechanical latch, only the floor plate latch is reliable. Disregard the fact that every modern military rifle uses a detachable box magazine.
6. The Remington 700 is unreliable regardless of the fact it is the basis of the USMC M40 sniper rifle for 40+ years with no changes to the receiver or extractor and is the choice of more military and law enforcement sniper units than any other rifle.
7. PF actions are not suitable for a DGR and it is irrelevant that the M1, M14, M16, & AK47 which were designed for hunting men that can shoot back are all PF actions.
8. 95 deg F in Africa is different than 95 deg F in TX or CA and that is why you must worry about ammunition temperature in Africa (even though most safaris take place in winter) but not in TX or in CA.
9. The size of a ding in a gun's finish doesn't matter, what matters is whether it’s a safe ding or not.
10. 1 in a row is a trend, 2 in a row is statistically significant, and 3 in a row is an irrefutable fact.
11. Never buy a WSM or RCM cartridge for a safari rifle or your go to rifle in the USA because if they lose your ammo you can't find replacement ammo but don't worry 280 Rem, 338-06, 35 Whelen, and all Weatherby cartridges abound in Africa and back country stores.
12. A well hit animal can run 75 yds. in the open and suddenly drop with no initial blood trail, but the one I shot from 200 yds. away that ran 10 yds. and disappeared into a thicket and was not found was lost because the bullet penciled thru. I am 100% certain of this even though I have no physical evidence.
13. A 300 Win Mag is a 500 yard elk cartridge but a 308 Win is not a 300 yard elk cartridge even though the same bullet is travelling at the same velocity at those respective distances.

SnellstromMaybe some text to explain what we are looking at Dogleg....
05 September 2016, 18:42
Dogleg139 grain GMX 7mm launched at 3500 fps from an STW and recovered from a short range bull moose.
I thought a picture was worth 1000 words?
05 September 2016, 19:08
Mike_DettorreI would have expected the bullet to come apart.
If I am going to have a bullet not "function" that is the non-function I would want. Nothing produced by man is 100%.
Do you have other recovered bullets?

Terry BlauwkampI used the 165 gr GMX in the 300 H&H on African game, nd they worked just fine.
Remember, forgivness is easier to get than permission.
06 September 2016, 06:18
SnellstromSo far I've just shot the .284, 139 grain GMX into sand and water jugs.
Excellent deep penetration and mushrooms just like in the catalogs.
That's why I asked about the picture, it looks like it was way low on velocity.
The way they penetrate in jugs and sand I'd have a hard time imagining ever recovering a bullet.
06 September 2016, 20:26
DoglegThe good thing about mono bullets is they usually exit; and since the evidence is gone you can write your own end to the story. That way you can imagine that it looks like your favorite letter, or lucky number, or that the retained weight percentage is the same as your mother in laws IQ. Anything you want, really. None of those are very important compared to whether after you shoot your game you are looking at it or looking for it.
06 September 2016, 20:55
COYOTE HUNTERI have used GMX bullets on deer, elk and moose. The only bullets I was able to recover were from a moose and they were just like the ads show.
Fortunately, they are very accurate out of my 7mm Rem Mag. They are all I shoot now.

KarooI am resurrecting this old thread.
Any new insights into the GMX?
According to Midway, the price of a 165gr 30 caliber bullet is the same as Nosler's E tip and only 10% cheaper than Barnes's TTSX.
Is the GMX worth a try?
What about accuracy?
Thanks in advance.

This happens more often with the mono's than people think, be it a Barnes, Hornady, or Nosler product...
28 August 2018, 17:01
shootawayI think they need to hit fluids or to open.

What?
The first inches of most game are hide, hair and bone... that's where expansion must begin.
29 August 2018, 22:15
KarooIt seems as if few people have experience with the GMX bullet and my conclusion would be to stay with the better-known monolithics.
Pity, as Hornady has a reputation for accuracy.
Any more comments?

You're thinking of the Barnes X type bullets.
The GMX is plastic tipped.
Force ( pressure) needs to be applied to the cavity of a HP projectile to cause it to open.
if the aperture is too small the pressure is not sufficient and it does not open.
this is why the US military can get around the Red Cross's ban on use of HP bullets in warfare when they ( the US ) uses HP match HP bullets in 30 cal sniper rifles.
in the past the Red Cross ( via updated conventions) mandated bullet use by design while today the rules are based on projectile performance criteria an not blanket design criteria

Mike_DettorreThe bullet shown by dogleg may have deflected off something and entered the animal in keyhole fashion.

IMO the Barnes TTSX, the Hornady GMX, and the Nosler E-tip are all equivalent in performance.

clayman216At ten percent cheaper than TSX I will stay with TSX. Shot animals all over the world with TSX and never had a failure, why change.
