I started about 3 wks ago, made a couple of mistakes at first. Make sure you set the dies correctly , instructions, you tube, and CGN is great for that. I'll tell you something that I never mentioned here because , well just because. Bring a small tap and die set with you , in case you get a case stuck in the die. ( it may never happen to you). I had one stuck and you ain't getting that sucker out in a hurry. One somehow got in without the lube. I have 2 manuals , Hornady and Speer and use them both. It's not that complicated, just take your time, read what's important in the manuals, ask a lot of questions. I'm heading to the range now , with some .223 I've made . I've got 22-50, 308 dies also , but haven't used them yet. I also have .45 LC dies in the mail. So google stuck cases you'll see what I mean. Calibers are important , I use mine all the time. Best of luck, and take it easy... Brian
