Worst: Steel cased anything; WWB is really dirty (in any gun) and will likely negatively affect performance.
Best: YMMV, try a variety and use what works and makes you happy.
For carry: in my 9mm (though everything has worked thus far...) I like Golden Sabers in the heaviest configuration possible, i.e. 147gr. Simple matter of slinging as much lead as possible toward the BG to inflict the most damage possible and stop the threat with the least defensive action.
For the range: cheap and clean (cheap? yea right ). I use the red boxed Federal from Wal-Mart, it's been great stuff and at $10.50/50rds, it's hard to find a better price anymore, and prices are allegedly going up over the next several months again.
