650 brass prep toolhead setup question

[problemchild]

I currently have my 650 loading done with 2 toolheads.

Head 1: Carbide sizer, (deprime, neck size), Trimmer (and external sizer die that goes with dillon trimmer), M die (size neck and knock off inside bur).

Head 2: Universal decapper (flush hole of corn media), powder die, seater die, crimper die (set to just kiss neck edge maybe .0005)


My question is this. On head 1 I am neck sizing down/up (station1) then down (station2) and then up again (station3). Should I run a decapper only in stage 1, then trim/size and then full length size including neck to remove one neck sizing (from station 1) off the equation?

Unfortunately the dillon 1200 trimmer also sizes the outside but cannot do the neck. I use my dillon carbide die to bump shoulder and FL size the base of the brass. I do not have the dillon trim sizer set up very tight so its only holding the brass firm during trimming.

Running the carbide sizer die first makes the brass go into the steel trim-size die much easier reducing press handle force. I like carbide and titanium carbide dies. Less effort and less fatigue over many thousands of rounds.

You got me all confused.

What do you mean the trimmer doesn't do the neck? Sure it does, The Dillon trim die is meant to size and trim. Seems like you are over working the brass.

Head 1
Station 1 decap die
Station 3 trimmer/sizer

Head 2
Station 1 carbide sizing die set shallow enough only to clean primer hole. Carbide ball sizes neck.

Sorry. I cleaned up the 1st post.

I see. I have an issue with the dillon trim die sticking a bit when doing all the sizing work. Thats why I size before with a carbide die. I only use the trim die to hold the brass while I trim and not size.

Now that makes sense. I do it the same way but I move the neck expanding to the loading cycle.

I have read other people do it exactly like you. I think raymondmillbrae's videos show your way as well.

I want to change two dies. Instead of the carbide sizer first I want to run a decapper 1st. Then I will move the carbide sizer last and take out the primer punch pin. I think he has the sizer 1st and the M-die last with trim in the middle.

1= punch primer
2= trim
3= FL size/neck size as well as taking any burs off trimmed neck.

You have to FL size before you trim because its the pushing back of the shoulder that causes the case to lengthen.

OK I learned something new. Not even dillon tech support knew that.
