Last year I had incredibly bad experiences with the 150 gr. Winchester factory Powerpoint loading in the .270 Winchester. Absolute and total fragmentation and less than 1.5" penetration on a close range whitetail and maybe 2" of penetration on a coyote at 100 yards. I'd like to try the new GMX and see how it holds up and if it really does foul less than its copper competitors (Barnes X).

Does anyone have any experience with it? How about data for the .270 Winchester?

The couple GMX bullets I have seen recovered did not loot like they performed as well as E-tips and Barnes, but I havn't seen as many of them as the others. I know the E-tips are excellant bullets also. I'd like to hear what you find with the GMX as you go along.

I am also interested as there is so little info on the GMX on this site.

this is just my opinion but I think these bullets are better when used on bone. I personally have never had a problem with Barnes bullets opening on soft tissue only and I've never lost an animal while using them. Since there seems to be questionable performance with these monometal bullets not opening up (as evidenced by hunters experiences), I think it would be better to aim at the shoulder bone, unless you are one to not like to damage any meat (which isn't much).

You definitely need to try a better bullet. Consider Remington .277 caliber 130 gr. Core-Lokts. My take so far this year with it so far this year is a dear, bang flop at 280 yards, a deer bang flop at 150 yards, another deer at 202 yards took two shots because the first just spined it and, today a crow at 160 yards. Now that's penetration and just a bit cheaper than TSX and GMX bullets. In addition, with IMR 8208 XBR fouling is less than I've seen with about any other rifle I shoot.

130gr Core-Loks

No offense, friend, but I have a very hard time believing this!

Can you fill in the blanks a little for me?

Fix or six years ago I missed a deer and hit a Jackpine at 40 yards.

Same load/bullet as you describe, but it center punched 8" of sapwood and kept on going.

Best wishes,

Sure thing. The .270 is an early Remington 700 BDL that my dad shoots. He is the one that actually had the problems with it. The first incident was a whitetail doe at 12 yards, broadside. When he shot, the deer was knocked down, got up, and ran off. We looked for over 4 hrs and found ZERO blood. There was, however, a swath of hair about 7ft long strewn across the ground.

The second incident was a coyote shot from our front porch. He was after some of the guinea fowl that we keep on the place. My dad shot him in the neck (as the rest of him was obscured by a tree). The coyote went down immediately, but when I went to take a look at him, he was still very much alive, just immobile.

The weird thing is that we've used
Powerpoints in both the .270 and .30-06 for ages and killed tons of stuff. This is the first problem we've had with the bullets. Unfortunately, that is more than enough for me never to use them again.

P.S. I've already ordered the GMX's and am going to give them a try. I've used Core-lokts too before and had pretty good luck, but want to try something else.

I just got two boxes of 270 Win 130 GMX Superformance and will give them a try on the range this weekend. As far as game perforamnce, they will have to wait until next year for Plains Game in Namibia.

That is wierd!

How is the gun shooting off the bench? Any key-holing or anything strange like that on paper?

If not, maybe it was a bad batch of bullets?

Hope the GMX's work better - I'd be interested in hearing how they work for you and Terry B.

From Hornady's ads, I wonder if they'll open quickly, especially when the velocity drops off...Look forward to hearing from people this fall as to how they perform on game at extended ranges from non-magnum carts.

Good luck - here's hoping for more success this fall!

If you're just looking for a good deer bullet, why don't you give the Hornady 130 Gr. Interlock Spire point a try. I've been using them for years in my .270 Win with great results on deer.

The bullets shot fine on paper. My guess is that is was just a bad box and there was some sort of quality control issue. I don't know if the core was pure lead, or if the jackets were abnormally thin or what. I emailed Hornady regarding loading data for the GMX and they sent me a copy of the .270 Winchester page from their manual. It looks like H4831 or RL 22 is what I am going to wind up using.
