How to Setup a Full length Sizing Die - Easy and Accurate

In this video I show several methods of setting up a Full length sizing die. I show my preferred method of .002" of bump and how to determine the proper dimensions. I also show what can happen if you just set the die and don't measure.

I recently started using the Hornaday comparator system. What a wake up call !

[H.R.]

Great video, when I do mine, I go in to the shell holder, and actually screw it out 1/4 turn, and slowly move it down until I get the desired bump.

Good info, I just take fired clean cases, punch the primer out then keep setting the shoulder back untill the lever or bolt just closes easy, then give it touch more. And then run all cases through the die.

Great video. I really like your approach of finding data, and appreciate you leaving it up on screen for a longer period of time.

Whenever I want to get into reloading it’s videos like this that throw me off…so technical and behind every second sentence it feals like the narrator means „if you don’t do this perfectly, your gun will blow up an you will certainly die..“

I’m going to start using witness marks on my sizing dies. Great video as always!

[tS-snjt]

Great video finally someone who explains headspace…

I highly recommend the Redding competition shell holder kit. Just get your die screwed in where it's close and then start with the highest shell holder .010". Not enough bump? Use the next smallest shell holder until you get the desired .002" set back.

I liked the methodical way you demonstrated resizing fully, without the expander ball, and without touching the neck at all. I had taken the .002-.003” shoulder bump as a given. Now I am confident that is a reasonable approach.

BTW for an M1A semiauto I push the shoulder back .004-.005” to ensure function. That action is really hard on brass and they will only last 5 firings anyway.

I set my FL Die to where it just starts to cam over. Then, I use Redding Competition Dies to determine shoulder bump. Works well because most brass brands do not bump the same and it keeps me from having to adjust the dies all the time.

This was the most difficult video to understand. I can only imagine that the video was designed for people who were already reloading not for the novice or first time Reloader…!

Could one use a feeler gauge to set space between the shell holder and the bottom of the die body for a more accurate setting rather than the dial caliper jaws ?

[cornbreadburgess]

Thanks for the video brother, see you on the next one, this will help many folks including me great info.

[AirborneSapper]

Wow !!!! Great Video Excellent Job !!!! Keep up the great work.

[craignmz]

Great video. Measuring is critical! I have one die that in order to bump my shoulder .003 there is a pretty hefty cam over. You need to measure it whether it is with a comparator or in your chamber.

I'd like to respectfully mention that most of the questions being asked would be solved if you read a reloading manual.

The Lyman reloading manual is my go to.

I'm using a Lee FLSD with an after market lock ring. I find that between the beveled edges on the ring and bottom of the die, and because of the threads causing the ring to be slightly tilted, the only way to get a consistent measurement is to measure in the same place on the ring, like in line with the locking screw. Also, i find it easier to put the square end of the caliper on the bottom of the die and using the blade to measure to the ring.

Great video as always keepem coming brother!!!

Firstly, thank you for your videos. They’ve made the jump into reloading much easier.

So long story long, I’ve just sized my first batch of brass using a Coax Press and Forster full length sizing die. I don’t aneal….yet.

I did measure all my norma once fired brass with a Hornady head space gauge and the consistency was within .0005

I set up my die and walked it in until I was at .-.002 vs my fired brass.

I then started to press the rest of the brass and the consistency on the headspace gauge was between -.0015 to -.0025

Is this to be expected without anealing or could the inconsistencies be coming from somewhere else?

Any perspective would be much appreciated. Thanks again!

Another informative video. You mentioned that the head spacer used was Hornady D400 but 6.5 CM uses C375 I think
