I had a sst 139 grain bullet blow up on a doe with a shoulder shot with a 7mm08 superformance at 70 yards. My cousin just shot a nice 8 with his 7 mag with 139 grain sst superformance. He shotvit in the heart and it didn't exit. It dropped the deer and left a softball size hole at the impact. This year I ordered a couple of boxes of the eldx's for my 300 win mag in 200 grain and some 150's for my 7mm08. I ended up liking how they grouped so I ordered a custom turret for my vortex viper on my 300. I shot a 8 at 200 yards and dropped it with the 300. It made a nice exit and the rib cage was damaged pretty bad. I shot a doe the next week at 60 yards through the lungs with the 7mm08 and it ran about 50 yards and had a bigger exit hole than what the 300 made. And it was equally as devastating on the deer when I skinned it out. They are my new favorite bullet.
