Hi cheeta264,

When you want to make comparison between different calibers and cartridges it is a more valid comparison if you choose bullets of "similar sectional densities" for the different calibers.

A very good site to provide lots of the information you are seeking is:

http://www.chuckhawks.com/index2.guns.htm

When you reach that page look for the "general information" section....and the rifle cartridge section...in particular. If you spend a little time absorbing some of the available information...you will be much better informed prior to making your decision. And even though the author, Chuck Hawks, has preferences....he does an outstanding job of providing impartial information, (which is NOT always the case on some of these threads).

I hope this information helps!
