I just started reloading 44mag and 44 special. I got an RCBS rock chucker supreme kit for 360, shell holder, powder stand, powder trickler, impact bullet puller and tumbler (used) for another 240.
So start up for me was about $570.
Loading with Hornady bullets (about $47 and $42 per 100) my cost per round is about $0.67 for 44m and $0.63 for 44s.
The kit came with a Nosler reloading book and there's lots of resources out there. There's a Facebook group call the reloading room with over 30k members. It's a handy group for all sorts of questions.
