Re: 308 and 338 reloading
RCBS Rockchucker works fine for .338LM. Plenty of leverage. Only thing is when seating bullets you have to tip the cartridge into the die before putting it in the shellholder because of unseated length.
There are tons of firearm forums with good sections on reloading on the net. The reloading forum here seems to tend toward more experienced reloaders. Not that questions aren't answered, but most of the threads don't go into basics like some of the forums.
I agree with getting at least TWO good manuals and reading them (At least the introductory sections) prior to purchasing equipment. I purchased the RCBS Rockchucker kit when I started and it has never caused me any trouble. Unfortunately if you are starting on reloading, be prepared to spend some money aquiring things not included in a kit. For a quick list of extras you will probably end up getting even if you don't take my word for it are:
Calipers (used all the time, get good ones)
Loading blocks (Get caliber specific ones for about $5 from Midway the blocks included in kits are one size fits all and pretty much are useless)
CASE GAUGES!! Can't stress that enough for a new reloader
You will also need dies specific for your cartridge calibers. Get good ones, don't scrimp on these.
For a good beginer forum try:

Plenty of sticky threads for beginners with a ton of lists and info for people just starting.
Good luck,
