Re: hornady 50 cal. reloading
Buy the RCBS. Mine has loaded over 15K rounds. REALLY GOOD 50BMG tools aren't made by ANY of the major manufacturer's. CH4D is my go to for top notch dies.(neck sizing bushing dies are SWEET) K&M manufacturing too.They make the best case prep tools out there.
The money you save on the RCBS you can by other stuff. PS-don't bother with a powder measure-they are more a pain in the ass than anything else-most 50BMG powder(if extruded) has HUGE kernels that do NOT meter well.
The RCBS 10-10 scale is GTG.
The Mechanic is on the money with his recommendations. ESPECIALLY that collet puller. (You need the Bullet sizing die too if you plan on shooting surplus projectiles-they need to be checked even if they are allegedly sized when you purchase them.
Shout out if you need help.
