What's currently the best reloading press for pistol and rifle, money no object?
This will be my first reloading press.
The post above by BSGA is good advice. I started loading my own ammo about 45 years ago and have been shooting competition since 1980. I still have my first press, an RCBS single stage. Without a competent mentor, a single stage press is the best choice for a first timer. Learn how to do it right, learn what can go wrong and how to avoid it, then if you want a progressive press you can add it to your equipment.
