RE: which is more powerful?
The 7mm Rem Mag is more powerful than the 30.06. It does have more energy and speed but it does blow the 06 out of the water. I always thought it was a ton more powerful, but it actually isnt alot more they are pretty close with the magnum having the advantage. The 7mm outperforms the 06 in penetration though. The 7mm has a long slender bullet compared to the short stubby 30 cal bullet. This means the longer 7mm bullet doesnt fully mushroom leaving a stem behind the mushroom to push it deeper, whereas the .30 cal bullet becomes basically a ball and slows down quicker. I shoot a 7mm rem mag and love it, i also had a 30.06 and wouldnt go back after getting my magnum.
