375 Ruger 250grain GMX

[brettp]

Howdy all,

I know people on here like crapping on Hornady bullets, but I never hear much about the GMX.

I am looking at the 250gr. GMX in 375 Ruger as a pretty darn good all-around plains game setup.

Does anyone have any field experience with it that they can share?

It looks comparable to a TTSX from Barnes, but of course it's not exactly the same.

Thanks,

BP

Should be as good as barnes ttsx. Has better bc

Are you a reloader or factory ammo person. I have a 375 Ruger but have never fired a factory round out of it.
I know you want experience with GMX which I have none of so I'll leave it at that.

I had one grenade inside a black bear last spring. Quartering down shot in the boiler room, didnt hit any bone but ribs. Left a football sized exit hole and we found peices of the bullet in the hind quarter.

Wow. That sounds more like what you'd expect from a spire point!

It's a great bullet! It acts more like a cup n core bullet than the tsx in that the 6 petals open into a more conventional mushroom. But unlike a cup n core it stays together at a wide range of velocities. I still prefer the ttsx because it expands down to 1800FPS. The gmx requires about 2000FPS but 2100 really opens it up.

That sounds like either a tumbling bullet or hornady really dropped the ball on the alloy for that batch of bullets. What caliber? Distance? Muzzle velocity?

Junk. Had one split up on a leopard, dead cat with big holes, but terrible bullet performance. I have some fragments taken out of the cat.

Used them on eland, non expanded and bent bullets. Busted up fragments, several shots but either blown up bullets that didn't penetrate or non expanded with small wound channels.

I think they might be great if you get a good batch but from many reports on this site, even by those who have defended Hornady, they seem to have no quality control and inconsistent results throughout at least the larger caliber bullet offerings... They do have a fantastic marketing plan.

I've communicated with several people who have contacted Hornady to discuss bullet failures and the only consistency seems to be the denials of any problems and unwillingness to even consider they have any problems.

My experience was with 250 grain GMX in 375 H&H.

I load a Peregrine 250g in my 375 Ruger Alaskan , it shoots MOA at 100m at a speed of 2650fps , I have not used the rifle in the bush yet , but do intend using it this season.

Are you hand loading or buying Hornady ammo? If you are handloading maybe you can work up something you will be satisfied with. Unfortunately many of us have had terrible luck with Hornady ammo for the .375 Ruger. I had major accuracy problems with it. Worst I've ever experienced. I went with Safari arms custom ammo and 300gr Nosler Accubonds and 300gr North Fork Solids and it has performed very well for me.

Haven't used this one only DGX.

Swift a frame 250 gr 375 ruger. From duiker to cape buff. This ones from a blue wildebeest.

Hornady Ammo. I think I'll stick to the factory swift stuff. 300g A-Frame and solid.

We've killed dozens of animals with the GMX and it performs as you'd expect a mono metal would, it penetrates deep, expands to 2X and holds together and surprisingly has been really accurate...not something normally associated with mono metals. As someone already pointed out, the six petal design does offer more frontal area as well. I shot a cape buffalo last year right in the shoulder and the results were impressive. Yes you do need 2,000fps for reliable expansion but out of a 375 that a heck 0f a long ways out there. Way longer than most people shoot!

Unless you plan on shooting past 450 yards sub 2,000fps impact velocity is really not much of a concern.

I like to have a margin of error so for a gmx I would want my bullet about 2,100-2,200 to get a full mushroom. Depending on caliber, that might limit you to 200-250 yards. My 120 ttsx is only leaving the barrel of my 6.5X55 at about 2700.

Now in a DG gun, I totally agree with you. You will never be shooting very far. Also, the larger the diameter, the easier it is to get a bullet to expand reliably so the GMX is a great choice. I also like the Barnes bullets because of all the relieving grooves cut into them. That is something I think Hornady should jump on.

 

[sheephunterab]

There honestly aren't many common hunting cartridges that you wouldn't get 400 yards out of and most 500+. When you actually start running the numbers, it's not a big concern unless you are a long range shooter. Even with the TTSX, I'd say 2,000fps impact velocity is a better minimum but no doubt the larger nose cavity does allow for slightly easier expansion. The GMX does have Crimping Cannelure and Pressure Relieving Grooves already. It always has. The original TSX didn't and that lead to fouling and pressure issues.

Here's a GMX recovered from a giraffe shot at 386 yards.

 

[sheephunterab]

Oooops...should have read 286 yards.
