I guess I can add something to this thread finally!
Was hoping to make it to the range yesterday but work sucks and got out late so I set up my 223 toolhead on the Dillon. Got the swagging rod set (I think), primer seating to the right depth, powder drop at 25gr of Varget, bullet seating die OAL at 2.220 (hornady 55gr FMJBT). Figure I'll make 10 each at 25, 25.5, 26 then head to the range and see what happens.
I put the specs above so people can tell me where I'm going wrong here as a noob. Probably need to bribe a local pro with some beer to double check my work but wanted to give it a shot on my own.
ETA: already sized and trimmed brass so I left the carbide sizing die off.
