Currently running a Dillon super 1050 with Mark 7 autodrive and sensors, currently waiting on a back ordered 2nd press so I'll only have the one press for the foreseeable future. I've been doing a lot of research but wanted to get some input from other people on what die I should be running in my toolheads. I'm starting with subsonic .300 BO and am starting with prepped, primed brass. We're mostly likely still going to trim and size the brass to our exact specs so on the first toolhead I'm thinking of running the following setup:
station 1: case drop
station 2: empty
station 3: empty (will have to disconnect swage sense so the rod doesn't interfere with primers)
station 4: empty (priming station, cases will be pre-primed)
station 5: empty
station 6: RT1500 trimmer which will also size
station 7: empty, kick out into bucket
Toolhead 2 for actual loading
station 1: case drop
station 2: empty
station 3: empty
station 4: empty
station 5: powder drop
station 6: digital powder sensor
station 7: bullet drop from Mr. bulletfeeder
station 8: Seat die, or DAA 2 in 1 seat & crimp, they don't make a .300BO die, but I currently have their 9mm/.357 die which I believe should work with .300BO as well, just not sure if I'll be crimping the rounds as well.
If we started to load unprimed .300 brass then toolhead 2 would have a universal decapper in station 2, swage sense and expanding rod in station 3 and priming in station 4
As far as .223 goes, my setup will approximately be the same with the exception of having a universal decapping die and swaging rods in stations 2 and 3 on toolhead 1 for brass prep.
I've loaded 9mm for a few months on this machine and it's been excellent, I've never done rifle rounds on a mark 7 autodrive so I just wanted to gather all the information I could from other users that are possibly running this same setup. If there's any die or pieces to the puzzle I'm missing, I'm all ears, and if there's any other tips or tricks to loading .223/.300 on a super 1050, I'm all ears to that as well, thanks.
