I would be a little concerned using this bullet on deer up close at those speeds.
Not really questioning the construction so much as I would be worried about just punching a hole through it with little damage being done.
The only reason I stated this is that in the past I have seen bullets at ultra velocities pass through with little damage on close in shots.
It has happened!
This was in a 264 mag.
I don't recall the bullet weight or make.
I don't know it they were premium bullets or not, I just know that it was a perfect shot and I helped track a wounded deer a very long ways with very little blood trail.
When we found the deer some 4 hours latter it was dead with an exit hole almost the same size as the entrance hole.
When the deer was capped the bullet had passed through between 2 ribs on entry and hit 1 rib on the way out.
The shooter had used the same bullets before only loaded to a lower velocity and never had that problem before.
He has since gone back to his original loading with complete success.
May have been a fluke, who knows.
I was just making a comment as to what had happened to him when he tried to increase to a max load.
