Picked up a box of Hornady factory ammo for my 7mm Wby, and took her out to the range today to sight in for my upcoming bear hunt. Quite impressed to say the least!
Rifle is a Mk V with a 24" barrel and all factory original.

Above the aiming point would be understandable, but to the right wouldn't be likely, for a final zero. The reason that I asked, is to see if the group pictured was just a cherry picked group, or if the other groups were similar. One groups says very little about the potential of a load, or a firearm.
 
Gilding metal vs copper is the main diffeenc,e then shape/ogive position, expansion shape, groove quantity and position....They are pretty similar looking though
 
While developing a load for my 280 Remington, I looked at both the 140 Barnes TTSX and the 139 grain Hornady GMX.
The BC on the Barnes was .406 and the Hornady is around .466. The TTSX was available and won out.
 
The GMX from what I have read is better suited for fast shooting rifles as Guilding Metal is harder than Copper. I myself will be using 180gr TTSX in my 30-06.
 
The TTSX isn't going to come unglued, regardless of impact velocity. I've been shooting them at 3300fps, and even with very close impacts, the worst that happens is you lose a few petals, but you still have a large meplat plowing through flesh with 80% of the bullet's starting weight being retained. The copper petals act as secondary projectiles in that situation, causing peripheral damage, as well. So you really can't go wrong, either way.

Exactly! I drive the 140gr TTSX out of one 7mmstw at 3500fps, and they work just fine on elk.

Do you not think the Horn GMX or any other Guilding Metal bullet will perform similar to the the TSX or TTSX Barnes bullets ? just wondering your opinion ! Thks RJ

I have no doubt that the GMX will perform similarly to the TSX/TTSX on game, but since the TTSX shoots more accurately in my rifles, that is what I use to hunt with. If the GMX was at least as accurate in my rifles, that is what I would be hunting with.

However, the E-Tip does not have a grooved shank like most monometal bullets, and it builds pressure at lower velocities than the grooved bullets.
 
I've yet to own a rifle that liked the GMX. I am sure they would do great, and would love to match them with the SST for practice and deer. They just don't seem to have the tendency to shoot as well as the Barnes.

I'm sure they're same/same when it comes to actual field results. The reliability of gilding bullets is the only thing I'd question, since they are a bit harder than pure copper. People have complained in the past about Barnes bullets not expanding at lower impact velocities, so I'm not sure I'd want to go to a harder bullet when considering the GMX vs TTSX.

But that's just academic. Field results are most likely indistinguishable.
