Nah the throat is further forward.....the chamber does not erode, and remains the same for the life of the barrel....lets not confuse things for the poor bugger trying to understand reloadingQuote:

The comparator tool the fella in the video is using is exactly what you need.
You asked how does one set the die back to 0.000"?
Thats easy - follow these steps.
1. Measure several cases that has been fired in your rifle.
2. Calculate the average length. This will be your 0.000"
While sizing you'll notice your cases will get taller(0.012" for example.)
Wind your die in and size, measure, repeat.
As some stage you'll notice (and feel) that the cases are starting to go shorter(pushing the shoulder back).
Once you reached - 0.002 to - 0.003 test the case in your chamber. Try NOT to go over - 0.004
STOP over. Thinking it.Quote:

I just use a gas torch in the dark. I rotate using a "holder" and count. But only the neck gets a bit of red glow. Shoulder only turns blueish. So reckon I need to give them another second or two.
I went out and measured about 30 223 and some 30.06 cases that had been annealed and FLS'd. Maximum variation was 0.003".
Next time I anneal Ill play with getting the shoulder hotter. But that will likely be some time now.
Eric reckons its actually fairly difficult to ruin brass.

Eric is right
I first began with old 303 in a lathe and an oxy-acetylene torch....they certainly glowed in the dark, but I now have a two burner timed annealer which can do 500 per hour. They are right you can really only ruin a case if it melts.Quote:

Just revisiting this as i pulled the faulty round today and prior to sticking it into my cases to prep I though i should ask how to reset it to push the shoulder out so it's usable.
Will another run through the press pull the shoulder forward?

Had this problem with some rounds inherited & loaded for his rifle.
Too long wouldn't chamber, so at your own risk as it's loaded ammo. Have a Redding body die, doesn't touch the neck can bump the shoulder & resize the case (lube required). Quick solution
But would that pull the shoulder forward?

Still got them, haven't tried them, only use them shooting paper so doesn't matter. The 308 has become a safe queen as got the the same 223 you have Many Thanks, cos u gave them to me.
What I normally do in a situation where the shoulders have been pushed back to far is to run the case over an expander about 0.5mm larger in diameter. Then size the case again.
Stopping about 1mm above the shoulder to create a false shoulder. Load and shoot.
G'day,
I have had multiple misfires using Fiocchi ammunition [.222 Rem] in one of my old Anschutz 1532 rifles and occasional misfires in my relatively new Weihrauch 60J rifle. The headspace has been checked in the Anschutz and is within specification. The HW60J is about 6 years old and has not had great use. My other Anschutz 1532 fires the Fiocchi without any issues. Firing pin protrusion in the misfiring Anschutz is within specification and it has a new spring in the bolt also. I did wonder about the primers being a little hard??? Fiocchi is apparently made to conform to SAAMI standards. I did measure Fiocchi casing and found greater variation in dimensions of the casings than with Remington cases. The misfired rounds have always fired the second time around after waiting a minute or so. I now use Federal ammunition in the Anschutz without any misfire problems.
