Well said, Poobs.
Just looking at the Etip, it puts me in mind of a Barnes X bullet, prior to the TSX treatment, but with the "T"Tsx treatment.
Admittedly, I have limited experience with the Barnes bullets, but IIRC, they cut the rings on the TSX to drop pressure.
Regardless, I am a fan of the barnes bullet, as long as the cartridge/rifle I am shooting it out of, can make it fly at 3000 fps or more.
The 270 WSM and 6mm Remington living here are a couple of examples of cartridges that work well with the solid copper bullets.
