.223 case trim down size?

[Kmcinnes]

I just switched over my Dillon 650 from 9mm to .223 for the first time since I've had it. I have been loading pistol rounds for my sons competitive shooting all year and I'm not real experienced with rifle reloading on the Dillon. My question is what length do you trim your .223 brass before running it through the press, I would assume that if I trim to speck once it goes through resizing/depriming it will be to long again? Am I off on my thought process?

Personally I would run it through your Dillon and just size it, just size and deprime. And then trim it, and chamfer it, tumble it... And then run it through the Dillon and load it the second time through. without the sizer die in place. I trim to 1.750

Trim AFTER Re-size...

I'm not really sure of your Dillon 650 system, I load all my rifle on a RockChucker single stage. I DO know that you want to trim AFTER you Full Length Size.

Your cases will lengthen after they are full length sized, so you need to trim to 1.750" AFTER the re-size...Bill.

With his Dillon he can easily just size and deprime, either you can use another tool head with just the sizer die installed or
back out the seater / crimp die and leave the primer tube empty along with a empty powder measure.

With using the progressive if you have a case feeder you will size and deprime in no time..

I don't trim, until I've sized. For SAMMI 223 Rem you can expect to trim after the first 2 sizings if you move minimal brass.

As has been said, you will want to trim after sizing. But once that is done, I believe trim to length is 1.750, with a minimum length of 1.740. But I'm not looking at a manual right now. Yours will tell you on the first page of the load data for .223.

The only suggestion I could make to this would be to switch to a Carbide Expander Ball.

After doing a little more research, I found that since I am running them in an AR with and the chamber being so long in the AR, that I really don't have to trim them at all. I loaded up 50 rounds last night and ran them through the gun this morning with no issues at all! So I should be ready to crank out another 500 or so with some confidence. I will need to run them through a couple other .223 guns that I have to verify if they will run through all of them that way, but at least for the AR used to test (which is my my temperamental of all of them) everything went great.
