Your in luck hunter 1!\
Today , there are multitudes of videos and manuals on line to get you started.
Back when I did ( mid 1960's ) it was by copying others work and loads. Loads found in dusty manufacturer's manuals.
But with all advice, beware!
Use common sense! If it seems risky, don't do it.
Let another blow his gun and fingers.
Are you going to load for rifles or pistols? Or both?
Pistols can be reloaded with a single stage press, but if you like to shoot as much as we do you will soon want a progressive set up.
but another warning:
It can get addictive! ( and not inexpensive )
But it is also rewarding to hunt or shoot X rings with ammo created with your own fingers.
