Empty resized case won't chamber

[FUNCTIONAL]

No.

If you measure the case length, the shoulder length, the base and shoulder diameters of a fired and sized case the problem becomes immediately apparent. Casting the chamber is not required.

Case length and shoulder length 100% agree with and recommended to him earlier. His problem is it not fitting and there were no marks on the marker test, I can't see how those measurements would help.

If he had some case head separation, bulging or any type of marks on the brass with marker those measurements would be needed but none of that is his problem.

Edit: I'm curious what you are looking to compare the diameter measurements to.

A case fired out of his 700 chamber.

I'm not going to reread this thread but I have to ask :
Does an unsized, fired case (fired from your rifle) chamber in your rifle?

If it does, and doesn't fit after sizing, you're pushing the shoulder forward.

If the Sharpie thing didn't work, lube a case, smoke the entire thing with a scented candle and then try and chamber it.
It will rub the smoke off where it's tight and even where it makes contact with pretty much anything.

Two different rifles, you probably should have read the thread.

Ok, so all pmc brass, measurements are listed as below. And what they were fired from. The fired from rem 700, untouched brass goes in like a glove. The ar brass and ar resized, do not. The resized is run through a Redding small base due, then through a Redding fl sizing bushing die. A bushing came in and was installed. .250”. I tried a dry erase marker test, but my fingerprints took a lot off so it was hard to tell. Tried it with a sharpie again but no signs of wear even though it’s hard to get the bolt closed on the ar resized brass. I know I’m better off having dedicated brass at this point, but now I’m just so damn curious as to what is holding it up.

Rem 700

Neck .252

Shoulder 1.458

Base .374

Mid (between base and neck) .366

Oal 1.757



Ar

Neck .254

Shoulder 1.462

Base .374

Mid .366

Oal 1.756



Ar sized

Neck .250

Shoulder 1.459

Base .373

Mid .366

Oal 1.756

That’s what we call a “hint”.

As i said before, keep your 700 brass separate from brass fired in ARs. Acquire some quality brass (Lapua, etc) for your R700 (a precision rifle) and use blaster-quality brass for your blaster.

Stop trying to fit square pegs into round holes.

 

[Simonsza1]

Ar sized needs to go to 1.454

 

[918v]

Does the AR sized brass come to a hard stop? Or does it wedge itself in?

Is the case mouth larger in diameter than the middle of the neck?

 

[Snuby642]

In the op the numbers were different (1.468) ?

And I thought the ar had the longer shoulder dimension, which would be "normal".

 

[Doom]

Trying to resize cases fired in one rifle to barely fit into a different rifle is mostly an effort in futility, especially when the original firing is a semi auto. Set the die up per the instruction and take the shoulder as it comes. It should be sufficient to chamber in the 700.

Yea, I would call it a pretty hard stop. The numbers I wrote for neck were at the very end. On the ar sized brass in the middle of the neck they measure .2545”, and at the base of the neck by the shoulder they measure .256”.

Yea, the original post was a different member. I piggybacked on his thread years later to see if anyone had a solution because I was having a nearly identical problem; I didn’t want to start a whole new thread.

Two different rifles, you probably should have read the thread.

I did read it. It's from 2017.

In my last post I said I wasn't going to RE-read the thread.


All of these threads end up the same.
The OP has an issue.
He's told numerous ways how to troubleshoot it.
OP picks one of the 20 things to check.
Doesn't solve the problem and keeps asking questions.

Meanwhile ten other guys jump in and suggest buying all new shit.
One guy will always tell the OP to stop reloading because he's an idiot.

88 posts go by and the OP still hasn't checked the basic stuff or written anything down.

New guy comes in and says you can't solve this without doing a chamber cast.
Someone else suggests that Lapua brass will eliminate ALL of your problems.

Hopefully, someone suggests checking the air in the tires...

When it's all said and done, the OP has three new sets of dies, four types of lube, a new unnecessary go, no-go gauge, a box of Sharpies and a pile of brass that's too long and too fat for his chamber.

He's even more confused than before starting the thread.

@spife7980 is such a great guy for having the patience to wade into these threads every week.

Nice recap.

No where did I suggest Lapua brass will solve all his problems. I did suggest it as an option for his R700. All his problems originated from his decision to try and fit/run brass initially fired out of a carbine in his bolt gun.

I always keep one set of brass for each rifle i load for (or at minimum, keep brass fired via general purpose ARs separate from brass to be used in precision system(s) that accept the same cartridge).

That would solve his problem.

Whether you agree or not is another matter (doesn’t concern me one way or another) but if you’re going to refer to something I wrote at least characterize it accurately.

The rest of your post seems about right.

Then thats the problem, the neck dimension. Your 700 chamber will not accept a .254” neck.

 

[n0glock]

Old thread, but I will tell you what I do as a brass whore, I take fired range .223/556 brass clean it, lube it, and size using standard dies set to cam over a little per the instructions, then trim, clean again and load always goes bang in AR or bolt, this is blasting ammo accurate enough for the application, precision .223 starts with new brass and is only used in a specific rifle.

 

[Snuby642]

Full lenght resized brass is gtg no matter where you get it.

Range pickup brass (GFL lol) and a speer 17 cent bullet in an ar.

Edit: loaded on a dillon.

I wasn't referring to you specifically, it was just a generalization. It was based on reading a new version of this thread every week or two.

I do the same as you, brass group stays with one rifle.
That eliminates all kinds of issues.

Last month I did load up >500 223s from a large pile of range brass I've had.
I set it up to fit one rifle and then checked it in a couple of others. All good so I cranked away on the handle.

They will be fine for kids plinking and critter smacking, but that's about it.
Precision loads/brass are married to each other.

PROBLEM SOLVED!
I scored a whole range of used bushing sizes on eBay and they came in today. The next size down from what I had, .249”, and below all allow the rounds to chamber now. So I small base resize and bump my shoulder half the distance, then full length resize/neck size to .249 or less as bump the shoulder the rest of the way, and the brass chambers perfect. Thank you everyone for all the help! I’ll process a bunch of this brass and then keep it with this gun until it wears out and repeat.

Sorry, didnt mean to start anything, on all the car forums I’m used to over the years people get mad for someone asking questions with threads already started about the same questions, so I figured I’d piggyback on this one since I had an extremely similar issue.

 

[Simonsza1]

When it comes to reloading and being safe I think it’s the one thing on the hide where you get some legit answers without the bashing! Good group of guys here for sure.

You didn't start anything at all.
I don't have any issue with answering questions to help people.
It's almost comical how much bad advice is given out, that's why I posted that I did. It wasn't aimed at anyone in particular, just kind of a semi-comical pot shot at all the crazy suggestions.

Glad you got it squared away.
