Headspace vs Shoulder Bump

[Erik Cortina]

Anneal then size.

The reason for stripping the bolt is because if you leave the firing pin in, it will create resistance as the spring pulls the bolt back when it catches the sear. It will affect feel greatly.

Work hardening of brass is primarily due to the heated pressures and gases ironing the cases to the chamber walls when fired, hardly any from the dies.

Clean, anneal, then size. Is what proved to work best for me. I've tried annealing after and all I got was inconsistent neck tension.

Not true.

The body does not ever get work hardened - and heat and "Ironing" does not harden brass.

It is the necks that get hard from expanding and sizing and expanding and sizing.

If the stretching and ironing have no effect as you claim, why would we even have to resize?
There is stress and strain to the cases every time they are fired. How significant is dependent of the load and clearances. Resizing is a replacement of the elastic modulus to a clearance state, only to be messed up the next time fired.
You should do some research on elastic and plastic deformation of cartridge brass in the internal ballistic cycle, instead of posting balderdash.

Brass (as in cases) is annealed at least 6 times during the manufacturing process.

There is brass flow and brass stretch.

There is no room on this forum to discuss seating the bolt lugs, I have bolts that have no cocking piece, firing pin or spring. They are designed to seat the lugs. Seating the lugs is a good start when determining the length of the chamber from the datum/shoulder to the bolt face.

Then there are safeties, if the safety is on the bolt the pressure of the spring is on the safety, not the trigger.

Nonsense and double talk... "How significant is dependent of the load and clearances. Resizing is a replacement of the elastic modulus to a clearance state, only to be messed up the next time fired. " What a load of meadow muffins.

We do NOT have to resize the case - many shooters just neck size and that is to hold the bullet. I neck size for most of my rifles, and the bodies are not having any problems.

If the bodies were having hardness problems from all of those terminal conditions, then we would have to anneal the bodies - which is NOT recommended!

I do not live in a small world when reloading. I form cases, when forming cases it is recommended to anneal the case to a point that will be below the case body/shoulder juncture.

Out side of reloading there are individuals that work brass, they hammer, then anneal, hammer again and anneal again. Hammering on brass hardens brass. When I fire a case in a chamber the case gets hammered from the inside, the case gets hammered with as much as 65,000 PSI, again, hammering brass work hardens it. Then there is time measured in milliseconds. Pressure going from zero to 55,000PSI in 1.5 milliseconds is some serious hammering.

Then it gets more complicated.

Gee, Guffey, you are a master at taking things out of context, spinning them five times, and reintroducing them even further out of context.

How did reloading ever evolve as far as it has without you steering us in the right directions...

... I mean, "Then it gets more complicated." from there.

The whole thing is just overwhelming for us. PLEASE save us!!

Long before reloading and brass cases individuals worked brass, they found hammering on brass hardened it, then they discovered annealing, after hammering on their brass projects they annealed. There is nothing I can do about changing the methods and or techniques. I do not have an exemption.

I make annealing equipment, the equimpment I make and use is something I spun once.

You keep drifting further and further from the subject, trying desperately to salvage this mess... but you lack basic understanding.

We are not hammering - if what you said was true, then the bodies of our cases would shatter after some number of reloads, but people are getting upwards of 80 to 90 reloads (at high pressures)... the most I have gotten was 45 reloads on Winchester 22-250 cases, and they were not at all hard or brittle.

So somewhere you have gotten lost on your journey.

What is the brand of your annealing equipment - I want to make sure I avoid it.
