I have loading tool rangeing old Lyman and Herters , from Lee hand tools to Wilson, Widden ,etc .
I much prefer a beam scale- in fact I sold both digital scales long ago.
A digital vernier works great but for true consistent 100% accuracy a scale vernier rules . Most times it is not needed
I throw all my charges unless I am loading fir targets past 500 meters , then I weigh each one.
The only thing s person cannot have enough of in my opinion is Advice and help from knowledgable help and loading manuals .
It takes time to learn how to do things right and how just what matters and what doesn't when it comes to handloading .
A person can get themselves wrapped up in details that actually do not matter while ignoring other details that do!
We are all guilty of that and I myself am no exception !
As far as the kits go, the RCBS is a good choice to start with for sure!
