So....should I just not worry about it and go after my elk with the 7mm Rem Mag and save the money to buy a youth shotgun for my almost 10 year old twin boy and girl?

I honestly have a hard time telling much difference between what a 7mm bullet will do versus a 30 cal. If you can't tell much difference between a 325 and 300 maybe I should not even worry about it and leave well enough alone. I have killed two cow elk and one spike bull with my 7mm and 160 Accubonds. Just thought I might like a little larger frontal diameter to create more initial shock and "knockdown" if there is such a thing.
