my current set up is my lee turret bolted down to an old night stand

. Just got into 5.56 reloading though and need some new tools to reload rifle cases... stupid milspec primers. So far though the cases haven't expanded to the point where I need to trim them except a few. Need to play with the auto discs too to get the right powder drop as well as get powder and primers. Any suggestions for pimers? I've heard CCI #41 and I've heard #40's work as well but then i've heard NOT to use #40's.
