.223 brass processing with 1050 troubles.

[Number99]

So I seem to be having trouble getting consistent shoulder setback. First tried just running a decapper in # 2, FL sizing in #5 and trimming in #7. Didn't like what I was getting so I switched to FL sizing and decapping in #2 and trimming in #6. Getting about the same thing. Getting as much as .006 difference in shoulder measurement with a Hornady collet deal. I'm setting both dies with the plate full for sure. Kinda eyeing the swager maybe letting things tilt a little. This is crimped brass so I am using it. Any 1050 tips? Thanks.

Try just using the FL sizing/decapper in in #2. Then back off the trim size die enough to only have it trim. I have very consistent results with that. You may also want to check the swaging die/rod to make sure it's not lifting or pushing down too much.

Are you using the gage to ensure both the resize die and the trim die are identically headspaced?

Yes. I'm sure trying to. Seems like I can get them about right then I do a small run and they get inconsistent.

How much is the swager causing your toolhead to tip? Try backing off the swage backup until it stops hitting so hard.

If you are running mixed headstamp brass with different web thicknesses, thicker webs are going to cause the swage station to tip the toolhead.

Try sizing in 5 and trimming in 8. This keeps you from sizing on the station that suffers from swager tip the most, station 7.

You may also want to back out your main sizer a little and let the trim die do a little more of the sizing, this way there's only one die that is controlling the final sizing.

When I process brass I don't even use the sizing die. I deprime with a universal decapping die, size with the trim die and hit the case mouth with a Lyman M die. It works great for me!
