Hello again folks.
Thank you all for your replies.
I know there are more powerful rounds out there.  If that was all I was looking for I would have picked the .308 or similar.
It's just a personal curiousity about my favorite round.  I never really saw a need for a different round for my personal use, but as stated before, it would be nice the see what the round could really do with a little 'finessing' is all. 
I thank you all again for your replies, and I will take all advice into consideration.  Thanks for the help folks,
TIm
