Thats pretty much what I am trying to do. I know I will need dies but not sure which ones.
I have plenty of my own 5.56 brass so I plan to convert it to 300 BLK. My original post was intended to get opinions on how do that. This is kind of what I have come up with so far:
Trim with Harbor Freight mini chop saw using this jig http://www.300BlkTalk.com/forum/viewtopic.php?f=179&t=80801
Next I need to deprime, resize, and trim Not sure which dies to us but it seems the FL size/deprime die is what most are using. I have a Dillion trimmer so i guess i will buy this trim die and milled toolhead when they are back in stock. http://www.bradswarehouse.com/index.php?p=1_11_Trim-dies
Clean in my media tumbler and chamfer/debur as I see necessary
Then go into loading as usual. I thought using a neck sizer couldn't hurt anything, drop powder, seat, crimp if needed
