My M700 .270 did not like the ELDX at all but loved the Gamechangers. I have now killed three coyotes, three antelope and a large muley buck with the Gamechangers and would say that they are much stouter than the Gamekings of old. They tend to perform more like an Accubond. My daughter has killed a muley doe and three antelope with the Gamechanger in her 6.5 Creedmoor. Combined, we have recovered one bullet in total.
This one punched an antelope doe corner to corner at around 220 yards.
I shot this buck at 70 yards, quartered slightly away, and a steep down angle. The bullet entered high on the right side ribs and exited the left shoulder, breaking heavy bone.
By the exit hole, I am assuming that the bullet broke in two. Considering the impact velocity and having it hit bone, I will take it.
I have killed two deer at short range with ELDX, (7mm Rem Mag), and had a front-row seat to a 50-yard shot on a black bear with an ELDx.(300 WSM) They did the trick, but the entry wound looked like a grenade went off. I lost a lot of meat on a near side shoulder of a buck when the point of impact was behind it with an ELDX. The bear had an entry wound the size of a softball. On shots at 200 yards to 350 the ELDX has been less explosive and worked to my preference.
The Gamechangers have been solid performers for me so far. Having used the old Gamekings since I killed my first bull elk with a 270 grain Gameking in a .375 H&H Mag (1993) and 140's in 7mm Rem Mag and .284 Winchester, the Tipped Gamekings seem to be a good bit tougher in my observations.
Obviously, others may have had different results. Hope that helps.
