Getting around to thinking about a hunting load for my wife's 270 and I'm running into the GMX vs TSX thing. I'm gathering performance is fairly similar for both of these bullets so my decision is pretty much coming down to whether or not the GMX shoots like an SST as I would like to have a range load for her as well. Any input appreciated.

:cheers:
 
SST and GMX they are loaded to the same specs and often will shoot to the same POI. I like SST for plinking and TTSX for hunting.
Red tip for plinking Blue tip for hunting.

Don't want Berger in my burger.
 
I use 150 grainers (GMX) in my .300wm, and I use the exact same powder charges as I use in my lead core bonded bullets (accubond, and Hornady interbonds) . The box says to load to same as lead core bullets. (its 95% copper/ 5% zinc Gilding metal construction, so slightly softer than pure copper X bullets, which allows similar powder charges for similar pressures.
The only reason I haven't shot any in my .270 win is because of the glut of ammo I loaded up last fall, and I haven't shot but 20% of it up yet.
I can't wait to put a couple of boxes of GMX's on my shelf in .277

As for actual performance on animals, I have taken a 320lb bear and a male moose I estimate to be around 800 lbs on the hoof (with the .300wm) . Both shots were pass throughs and both animals probably made it a total of 10 yards combined. Wound path and performance seem to be equal to the TSX bullets, so I think they are a win!!
 
I loadedsome 165 gr GMX for my 300 WM last fall for my moose hunt and took down a moose that when dressed out was well over 400 pounds (I don't know what it was on the hoof, I guess between 600 -700 pounds), it took one of those 165 gr GMX to make the moose hit the deck, I love em
