223 not chambering

And then there is another gage called the chamber gage, I have no problem using a spare barrel or a cut off barrel that has been reamed to the correct chamber.

And then there is the straight edge that is used with a feeler gage or a flat surface that us used with the feeler gage.

Its already been explained a few times. I'll explain it again about setting the bullet seating die properly after you measure.

Ir first seat the bullet and then:eek: adjust the die to crimp, but first:) back the seater plug off. After adjusting the die to crimp readjust the seater plug.

It all goes beck to the reloader thinking he can bump the shoulder back and or move the shoulder back; for years and years I have insisted it is impossible to move the shoulder back with a die that has full length case support. AND NOW? I am convinced it is almost impossible for reloaders to keep up with all of the scuttle details of reloading.

Crimping requires the slightest hint of effort. A few manufacturers of dies and reloading manuals have suggest crimping and seating is a bad habit, the first one suggested more bad can happen than good. In the beginning they suggested crimping could have an adverse effect on bullet hold. Reloaders changed bullet hold to tensions because tension sounded catchy.

Per post #57 you have over crimped which causes the shoulder to buckle and expand. Simply back off the seating die a half turn and seat a new case and bullet.

Crimping instructions come with the seating die that crimps. First back the die off and then start seating' to the correct length. "AND THEN" back the seater plug out, after backing the seater plug out adjust the die to crimp then secure the die to the press with the lock ring. After locking the die to the press with the lock ring lower the seating plug until it contacts the bullet and then STOP! Secure the seater plug with the lock nut to the top of the die.

Or; do not crimp, just use bullet hold, if bullet hold is not available?:confused:

Hopefully now I measured correctly:

I don't have unseated brass as I did all 60 when I made this batch. Just going off the bought ammo and what I have already made (1st 3 pictures). Not sure if this would help or I must make a few brass? The next two are after re seating. But the last picture is the round when it was first seated and hasn't been re seated. But gives higher diameter. I measured the other groups at random and also gives me measurement of .3580"-.3590". Shouldn't it be the opposite where as seated again, from what you said would increase the diameter?
 
Reloaders as a group does not have an affinity to the datum; The datum makes life and reloading so easy and simple.

Again, I use take off barrels, I cut up barrels to make chamber gages, I use new barrels, my barrels are full of datums and I have reamers lots of reamers and I have access to 250+ reamers. And I am not the fan of crimping bottle neck cases.

When you started the cases worked, I have always suggested a reloader save a few new, store bought, factory loaded rounds for comparison.

And then the case appears to whip the press when it refused to be sized. When that happens I always want to know 'by how much'; I am also the fan of the feeler gage, When sizing a case and the cases refuses to be sized I measure the gap between the bottom of the die and the top of the shell holder.

There was a time the standard remedy for the 'difigulity' of sizing the case was to grind the top of the shell holder or bottom of the die to increase the presses ability to overcome the cases ability to refuse being sized. There are some reloaders that continue the practice and some have purchased Redding shell holders, others have purchases SKIP's shims. ME? I am the fan of the feeler gage, anything a reloaders can accomplish by grinding, special shell holders and or shims from SKIP I can accomplish with a feeler gage.

Since all your cases are loaded, you next need a bullet puller to disasemble some loaded rounds and resize the cases to restore the shoulder to its original condition.
 
I see Mr Guffy decided to show up.
OP, do whatever makes you happy.

But I suggest ignoring distraction for now. Focus.

1) Your resized brass chambered easily.Thats important. Your problem is not in the sizing die or operation. Your rifle chamber,as a gauge,proved that.

Putting powder in the case did not change anything,unless maybe you have powder in the case neck. Over compressing powder can be an issue.

2)Remember,the brass fit till now. SEATING The seater die body is a slip fit on the cartridge case. Brass should fall in,and fall out..It just holds and supports the brass for seating.It does not reform the brass.

Seating should not change the brass that easily chambered.

Except for one thing. The seating die will crimp the neck into the bullet.

And new reloaders don't think of that. So,instead of reading and following the die instructions,they intuitively screw the die body into the press till it contacts the shellholder.Bingo. Crushed case. But the eyes don't see it.

Next,they write a post in TFL "My .223/5.56 ammo won't chamber...."

Then people go back to talking about sizing and gauges and headspace. Mr Guffy shows up and tals about old milsurprifles with excessive headspace,he's the only reloader,and he has a quick draw feeler gauge.

All in the world I asked for is a measurement over the shoulder before and after you seated bullets. You can substitute a factory load or any flipping piece of 223 brass that will easily chamber.

I don't see why its so hard.

I believe the bullet scuffing was a red herring.IMO,collapsing the shoulder made the ammo eccentric. The bullet is off center.

I also believe something else.

3) My theory could be WRONG!! I'm OK with that. I'm happy to eliminate it as a possibility. Truth,not ego. That's why I asked for a measurement FIRST,

Could well be, but I doubt the OP has a concentricity gauge for the test.

Ninodesmente,

The easiest way to check this is to take a big Magic Marker and just coat a whole cartridge with it. Try to chamber it, then withdraw it. Wherever it is hanging up, there should be rub marks. That's way easier than all the measuring and its attendant potential for errors if you aren't used to machine shop procedures.

Per an earlier comment, when you took photos of the Wilson gauge, what was needed was a profile shot so readers could see if the case was proud of the higher step. The head of the case should be between the two level at the back. If you lay a ruler flat against the higher step, it should not touch the case. If it does, the case is inadequately resized. But since you chambered the cases before you loaded them, I seriously doubt that is a problem.
 
from page one:

First mistake?

--------------------------------------------------------------------------------

Quote:
When powder was added and bullet seated, the OAL came to at 2.2585"-2.2595". Now my first mistake was not chambering the 1st group I made. All of them fall at/below 2.2595".

I will disagree; the first mistake is not knowing the length of the chamber from the shoulder of the chamber to the bolt face. After that there is room for another mistake; A reloader can size the case and without a bullet and powder attempt to close the bolt. If the bolt closed the case has enough clearance to allow the bolt to close and the case is not bulged. The bulge in the case requires the case to be sized when the bolt closes.

And then there is the problem with crimping and seating. If the reloader does not understand crimping only requires a hint of effort he can create a bulge at the case body shoulder juncture/

I'm with this. Although some of the symptoms are those of work hardened brass, improper sizing actually makes more sense. I also agree with the scuffing theory It makes the most sense since it's an odd looking scuff.

I'm a little sensitive when it comes to work hardened brass since I just dealt with it so I probably jumped on that bandwagon prematurely.
 
In short engineering instruction:

1. Determine overall length option by doing the bare-bullet/cleaning rod test on Post #28. If over 2.250", proceed to step 2.

2. Do what ever you have to do to get an empty case. Buy one, pull one, pick up one... your choice.

3. Full length resize the case after screwing die down to ram -- plus ⅛ turn to minimize springback. Lock the die.

4. Screw the seating die down to ram, then back off at least one full turn to get away from crimp shelf . Lock the die.

5. With empty case, seat the bullet to 2.250.

Don't measure, gauge, anneal, or otherwise fiddle with anything at this point.
Just tell us if it chambers easily .
 
4. Screw the seating die down to ram, then back off at least one full turn to get away from crimp shelf . Lock the die.

I am not a fan of putting a new reloader into a dead run; if the crimp die crimps what is wrong with knowing where the crimp is located? And no, I do not expect an answer.

I suggest the reloader place a case into the shell holder and then raise the ram. After raising the ram I suggest the reloader adjust the die down to the case until he feels the die contact the case. Once the seating die that also crimps is adjusted down to the case the reloader can back the die off to prevent crimping.

Dillon and Lyman said crimping bottle neck cases is a bad habit especially when seating the bullet at the same time. Now I understand that is a mechanical problem: meaning, when the crimp is applied the bullet is being seated. With anything more than the hint of a crimp the bullet is moving down while the crimp is being applied. When the crimp latches onto the bullet the neck bulges and moves down. Back to the seating die does not have case body support: When the neck is shoved back the shoulder/case body juncture expands/bulges.

I know; reloaders learn nothing from this, reloaders insist they can move the shoulder back and they invented a new term with a blind of an old term called bump/ They bump, I can't because I find it impossible to move the shoulder back with a die that has full length body support. The shoulder can be moved back with a seating die because it does not have case body support. And I understand there is a company that is making dies that support the case body. And they think they are the first:eek:

Instruction #4: Modified

4(M). With seating die backed waaaay off, run an empty case/ram fully up into it. Screw die down until it contacts the case mouth. Back off 1-turn and lock it down.

It is only because I believe I have the luxury of disagreeing. And I know if I do not say something no one else will.

Way off + one turn: one turn is .017"+, I know you did not forget the OP could be having a problem seating bullets and the purpose of the seating die is to align the bullet with the neck of the case. I have old dies that were made before reloaders discovered the Internet. The old dies had a sliding bushing that set on the shoulder of the case when the ram was raised, my opinion the old dies did what they were suppose to and that was align the bullet with the neck of the case; there was nothing in the instructions about backing the die 'way-out.

Now there are competition seating dies, I have two with additional bushings with extended shell holders, again when it comes to aligning the bullet with the neck of the case I believe they do an outstanding job. I do not have competition sizing die because I have not found enough fault with the dies I use and that could have something to do with the way I use my dies.

And then one day I made a seater, there was no backing it out because there was nothing to back out but when it came to aligning the bullet with the neck there was nothing in seating that was more precision.

I have a silly question.
Did you weigh a bullet to make sure it is what is advertised on the box?

Had that issue with some SST's before. Box said 139gr but were actually 154gr.
Also had happen with 25 cal Ballistic Tips too. Box said 100 gr, bullet weighed 115 gr.
 
{Edited out snark. Let's not be trolling for flame wars with other members. In the end, you just wind up accumulating infractions.}

I recommend start over with an empty case. Pull the bullet with pliers if you need to (discard the bullet), size the case, measure it, report back here. This will rule out sizing as the issue, or not. Then walkthrough setting up your seating die. Then seating depth. Step by step, here.
 
Guffy also posts things like "And then there was. . . melt down the cannons . . . then powder the gators behind . . And blew the gators mind."

That was a quote that started out; "In 1814 we took a little trip along with Colonel Jackson down the mighty Missip". The song claims they melted their cannons down so they started loading up alligators, now that had to be tough on the alligators because the song writer claimed the gators nearly lost their minds.

An inertial bullet puller is inexpensive and would do that job without marring the bullet. But either way, coloring and marking the thing by chambering it will tell the tale.
