Well said BobinNH !!
I have noticed just that, smaller 7mm's can and do push lighter bullets just as fast or almost as fast as the big 7's do. But the 150, 160 and 175's there are a big differance.
Heavy bullets with an high BC fly further with more energy. That's why I choose the 150 Nosler BT. The only 160 I could find that was not constructed like a tank was the 162 Amax.(only hunt deer) But hard to find around my neck of the woods.
