Got to agree with Terry, get a single stage press. Learn the craft find out what you like , find out your gun can handle. Then after you have a grasp of what is going on upgrade to a progressive press.
The progressive press is great of cranking out ammo fast, ...But, you will find that once its is set for one caliber you will NOT want to change it ! I load 90% of my ammo on single stage presses. It is fast and accurate. The only caliber I load on the progressive press in 40s&w.
First and most important...NO distractions.
Second prep your Brass.
Third research , document and take notes. Use multiple loading manuals. Follow their guidelines.
Fourth...Take your time. Get a routine of the steps involved for your process. Change them when nessary. Don't be afraid to ask questions.
Fifth...When you are pushing the boundries of hot loads be careful...Temp, pressure, change of powders or primers will change the playing field. You don't want to be that guy ! Whose rifle blew up in his face.
Read the old posts in this section there is a lot of info to be had.
Good Luck.
