RE: Is it really worth it?
It depends on what you shoot & how much you shoot. If you shoot a 30/06, 270, 308, 243-----A couple boxes a year-----NO. If you a 375 H & H -----YES.
Loadloading to me is more of a hobby than an exercise in saving money. It will cut your cost per round but you will add expense in all the equipment---ie. electronic scale, electronic powder dispenser--etc. Plus add in what your time is worth.
There is a certain amount of satisaction in knowing that you rolled your own ammo & that it isVERY accurate & it worked to perfection on a 6x6 bull elk.
