BTW, the 30-06 will do anything the 7mm Rem Mag will do without having to resort to Light Mags.
and the 308win will do anything that the 30-06 will do
and the 300 savage will do anything that the 308win will do
and the 303 british will do anything that the 300savage will do
and the 30-30 win will do anything that the 303 british will do
and so on and so on and so on
The differences between each cartridge are small but they do exist and they do add up.
