Considering your interests in reloading .308 now and 50 cal and .338 Lapua in the future, I would recommend the
Lee Classic Cast press. For your .308 I would get the
Lee Collet Die set. The press comes with a priming tool, but most find that a hand priming tool is more sensitive, and you can get better results. The
Lee Auto Prime works well. You can go all out with case triming, but I find the basic
Lee Case Length Gauge and shell holder along with a hand cutter is all you really need. I prefer a balance beam scale to a digital scale, and really like the Redding #1, but it is discontinued. You may find someone selling it used. RCBS still sell balance beam scales which is another alternative. A Lee primer pocket cleaner, case neck chamfer tool is about it.
Not essential items but many find that a powder trickler like the Lyman one is convenient to add that last little bit of powder to the scale. And a powder measure like the
Lee Perfect Powder Measure is a good way to fill the powder scale to just under the desired weight. The trickler is then used to put the last few kernels of powder in to get the exact weight. Not essential but speeds things up.
