RE: Are bigger cartridges really better?
Not sure I can agree with you, but thats the way it is I guess. I just happen to think that even on marginal shots non magnum calibers can and do perform well. Heck I have made marginal shots on game (pretty sure everyone has), and they worked fine. How much is too much?
Like I said before though, if you want to use one what do I care. Do what you do and have fun doing it.
