Long Time Long Ranger,
Your Data is flawed. With a 26" Barrel the 7mm rem mag can easily push a 180 berger vld to 2950. I have done so in a remington sendero using retumbo. The 300 WM with the 210 and 26" can get 3000-3050 probably. Discredit all you want to, but realistically, there is not an animal on the planet that will tell you. Hey, your bullet was .024 smaller in diameter, I'm not going to die. This is nonsense. I have seen game shot with a 7mm rem, 300 win, and a 338 win mag. If you can seriously tell me you can tell which animal was shot with what by looking at wound channels i'm going to say your full of ****. Just saying, this is a rediculus comparison. If you really want to get technical, Berger is producing the 195 vld for the 7mm. Which, with a 7mm rem ultra, vs a 300 rem ultra, with a bc approaching .8. It will leave the 300 in the dust. With a 7 rem mag with an 8" twist, and pushing 2850. That will be a long range king. Say what you want. But ballistic superiority lies with the .284 caliber. I picked a 7mm rem mag for less recoil and same performance. And it delivered.
