I sometimes get myself into trouble when picking up a new hobby because I get all excited about it and then spend a lot of money in gear only to find out that it's not as exciting as I thought it would be. I am then faced with the problem of unloading the gear and salvaging what I can to recoup my expenditures. If you're like me, I would recommend that you consider this approach to reloading:
If .308 is all you're going to shoot and you don't know how serious you will be with shooting 6 months to a year+ out, you may wish to consider just buying the ammo and collecting the brass for now. You can still decide to reload if you're still in love with the round and shoot enough of it to justify expending the money. If you plan to only shoot a few hundred rounds, it may not be worth the cost and effort. You can compute the anticipated cost to buy a press, the dies, brass, powder, bullets, primers and, therefore, the cost of making your first to the last bullet. You can also compute the number of bullets you need to load/reload just to break even from a financial standpoint. If cost is your only concern, base your decision to proceed with your reloading plans on your computation If the cost to reload is significantly less than purchasing factory ammo, go for it. If not, just purchase your ammo. Of course, there are other non-quantifiable factors involved in considering whether to reload as well such as time, space, accuracy, fun, etc. Let these non-quantifiable factors be the deciding factor if the cost to reload/load exceeds the cost to purchase. Good luck
