Anybody try Hornady GMX 7mm-08???????

I Recently acquired another Tikka in 7mm-08 and was thinking about buying a box of factory ammo(superformance) GMX and SST to see how they perform. My father-in-law has a model 7 in 7mm-08, so I figured I'd buy one box of each type ammo and try them in his rifle and mine. He's interested in them as well, so we're going to go halves on the ammo. I'm curious if any of you fellas ran it through your chrono and how it performed out of your barrel. And if any of you tested it on any deer, antelope, elk etc.

Thanks,

BT

Re: Anybody try Hornady GMX 7mm-08???????

i also just purchased a new rifle and asked a question about some factory ammo and some people have said about trying the sst's in my 6.5x55. I've heard theyre real accurate but every rifle is different all you can do is try. As far as any ballistic tip style bullet is concerned i try to steer clear of them, just my personal preference. I like deep penetration and weight retention and something that if I hit shoulder bone it will shatter it and possibly not explode. But to each his own and good luck to you. The best performing factory ammo I ever had was federal premium barnes triple shocks for my 243 in 85gr. Absolutly devastating on deer. My buddy shoots the same in his 7mm-08 in the 140gr with the same results. To bad they dont make that for my 6.5x55 swedish.

Oh yeah tell me about, I to have a Swede and have yet to find a 140 grain bullet it doesn't like.

Yeah I used Winchester Supreme B-Tips before on deer out of my 7mm mag and it gets downright messy and I always ruin meat. I'm not interested in the B-Tips for hunting deer anymore. I'm more interested in the GMX. Thanks!

I have handloaded the GMX in my 30-06, and my dad has shot them a few times in his 7-08.

In the 06, I like how they did with deer, but my dad didn't hunt with them in his 7-08. They were superb for accuracy, though.

Another bullet to consider is the Interbond, as that gives the poly tip and associated benefits, but carries behind that poly tip a bonded core bullet that WILL penetrate. Same with the Nosler Accubond, which I use in my 257 Roberts.

TDD,

Thanks!

But I'm already familiar with Interbond and Accubond and their both excellent bullets. I'm mainly interested in the GMX. From what I've read, the GMX seems to be a pretty good bullet, but I am simply curious about some first hand knowledge that some folks on here might have had.

It shoots around 1/2" for me in my '06. Dad had similar results in his 7-08, he was just concerned the 7-08 didn't drive them fast enough to generate reliable expansion out at 200+ yards.

I shot 3 deer with them in the '06, all under 30 yards, and none left any indication of fragmentation or loss of mass.

Awesome!

Thats the kind of stuff I'm looking for. What make/model is your dad's 08?

Thanks!

Nice, I was wondering how those new Model 70's shot.

Here's the last group I printed with the '06. It's a 165gr GMX on 57.5gr IMR4350, seated 0.01" off the lands. That's 3 shots, and as near as I could read my calipers, that measured 0.485" center to cener.

The group before that measured 0.68" center to center.
