Home Forums Hunting & Shooting Ask The Gunwriters Let's Talk About Hornady GMX Bullets

Pretty good test between the Barnes and the GMX here:

http://www.soarraptors.org/Documents/CopperBulletStudy.pdf

Not much difference between them...according to this test.

The only thing I have shot with them is one antelope buck. It was a headshot so not much of a test of the bullet (165 grain .308 from a 30-06). In my rifle they are not as accurate as the Interlocks, but shoot around an inch and a quarter, at least in Superformance guise. Haven't played with them handloading yet, but hope to soon.

In my very limited experience I would certainly agree with this statement. 168 grain (moly) Barnes seemed to hammer AK game to include moose.

Dirtfarmer;
Good evening to you sir, hopefully this final Monday of January was an acceptable one for you.

So I think that I can now admit that I "once" had a .270 - at "one time" and have since had it rebarreled.

Anyway without looking at my hunting log, I know I shot at least 3 bucks with the 130 GMX and switched to the 130gr TTSX after a bit - partially because they shot a wee bit better and partially to see what difference there was - if any.

There was not much difference as far as I was able to ascertain from tissue damage or the one sample of each that was recovered.



I believe that the TTSX is on the right and the GMX is on the left. They both weigh very close to the same weight, again sorry I'd have to dig up the notes to get the exact weight but I don't think either one lost a grain.

The particular .270 barrel I had happened to be a slower than usual twist - 1:11 � as close as I can measure - and didn't give typical .270 velocities, so that might have some bearing on the bullet performance.

That said, if I traded into another .270 tomorrow, I'd have no hesitation whatsoever using either GMX or TTSX bullet.

Hopefully that was useful information for the OP or someone out there tonight - not that any of us would admit to using a .270.....

All the best to you this week Dirtfarmer.

At the risk of nitpicking, I think that's reversed based on outward appearances.

I shoot the 80 GMX from my .243 Win over 45gr imr-4350. Accuracy is 3/4" or less as long as I pull my booger hook correctly and the small sample of whitetails I've killed with them have been impressed. Complete penetration and blood trails that are heavy and short.

I shoot the blems from Midwayusa.

Thanks, Dwayne, for that heart felt .270 confession...

I know it made you feel better...

To me, monometals do best blasted at max vel. I don't like small caliber mono's as well as mid and large bore ones. I use Scirocco's, NPT's and similar in .224-6mm guns for WT's and hogs. I do like E-Tip 120's in my 26 Nosler, as I've posted already and the 250 TSX in my .45-70.

IF I was so disposed to work with a .270 (in the closet, of course), I'd consider 130 monometals at max vel. I think those would work pretty well.

BTW, the TTSX has driving bands like the bullet on the left...

DF

I'd even try the 110 TSX BT at 3,400-3,500 fps, just to see what it would do. The 130 version could be pushed around 3,100-3,200 fps. I'd want to see how they grouped.

Whttail in MT;
Good evening to you sir, hopefully your day was an acceptable one.

Thanks for the gentle correction, you know I knew which was which but so help me my fingers typed it wrong anyway....

It wasn't nitpicking at all and I appreciate your taking the time to help me get it straight.

All the best to you in the remainder of the week.

Dwayne

I thought maybe you were looking at the picture from the other side.

Dirtfarmer;
Thanks for the reply and the nice manner in which you conveyed my backwards post as well.

So far we had good success with 80gr TTSX in our daughter's .250AI which are the smallest monometal we've run and they've killed deer extremely well.

I'd add that in addition to velocity we've seen really fine results with monometals twisted fast in more moderate velocities such as our eldest daughter's 6.5x55.

Thanks again for the kind response and all the best to you.

Dwayne

Whttail;
Well I can see how you'd think that seeing as I'm on the other side of the medicine line and all.

Really I believe I'll need to stop posting later on in the evening when I'm that sleepy.

Thanks for the chuckle and all the best to you sir.

Dwayne

I did some primitive testing with .30 cal 150 grain GMX bullets

http://www.24hourcampfire.com/ubbthreads/ubbthreads.php/topics/7039270/2

Good accuracy (note those groups are at 200 yards. I will see if I can find a link to a video of young bison I executed. I think they work very well.

You bet!

I have three hunting loads always at the ready for any new 270's that might find a way to my house.

130gr TSX, TTSX, & GMX all over 60gr H4831sc. I can always find one load that will shoot around an inch and sometimes two or all three.

I have no qualms using any for hunting.

I have also used the 85gr TSX and 110gr TTSX/TSX succesfully out my 270's.

I see on Barnes' web site, you can run their 85 TSX at 3,800 fps, their 95 TTSX at 3,700 fps, and their 110 TSX at 3,500 fps.

Those loads should be real bombs on WT sized targets. I don't know how accurate the lighter ones would be, but these are some interesting combos.

How did the lighter bullets perform?

DF

I can tell you the 110 TTSX at 3400fps from a vanilla .270 does very well on pigs and a couple of blacktail. I can also tell you the Hornady 110Vmax takes the same loads, hit the same point of impact to 500 yards and are a heck of a lot cheaper to practice with.

Dead critters when we did our job. The 110's have taken numerous deer, hogs, antelope, a blackbuck and Axis.

The 85 was used in a reduced load for my son. 1900fps, 100 & 106 yard shot, complete pass through and two dead deer. I never pushed them hard, but should try it sometime.

What was the load? Where did you get the starting data? I tried to get some reduced load data from Barnes but was unsuccessful.

I used H4895 per Hodgdon website.

That's what gun writers are for. That's why they get paid the big bucks.

Shot two Mulies out west[Eastern Sierra's] with 165 GMX's from my Ruger MkII .30-'06. Pretty much dead right after the shot, about 200-225 yards. One didn't move, other than tipping over, the other staggered maybe 10-15 yards, plop. I don't recall MV, as my notes are packed for moving, but thinking 2850-2875fps might be about right. Powder was/is Ramshot Hunter: 59.5gr.
Hope this helps.
