Redding small base sizing die for .223

Anyone here use one? I'm having issues with my standard load with my new Rainier AR. The loads chamber but a noticeably harder to extract every few rounds. I use mixed brass for my tactical rifle match loads and think the slight variations from the once fired brass I recovered is the culprit.

Boxer I never used one. I never had the need in my ARs or anything else. I use the Redding full-size die and mixed brass and I am good to go.

I know the die will work if you have a tight chamber and need to get the brass down to the base sized.

I called redding and inquired about when I should switch from normal to SB dies when looking at 223 dies.

I was informed by someone at redding who sat on the board, or something along those lines, for SAAMI.

IIRC, only when you have a known cut on a chamber, ie. custom/tight chamber, should you then switch to SB die.

For your everyday ABC AR's that 99% of the people in America own that are "mil spec," the normal dies are all you need.

That's my issue one rifles chamber appears tighter then the other. I have several thousands of my reloads through my DDM4. The Rainier just seems realy tight so if the load is barely on the large side sizing wise it gets stuck.
I know it variations in brass, but don't wanto to sort by head stamp.

I don't understand what you mean by "noticeably harder to extract" with an AR.

Sounds like you need a "Lee Bulge Buster"

At the end of a stage when I remove the mag and pull the charging handle it's hard to pull the round is partially stuck. I measured the cases that had issues at the base they are. .3735 to .3745
Factory XM193 is .3730 and my barrel is .3730
Does anyone know the milspec min and max for a 5.56 chamber and round at the base?

Sorry about that, couldn't help myself.

Maybe these drawings will help:

Yeah, seen that drawing it shows .3769 as on the base. My chamber is .373 and the reloads that get tight start at .3735 - .374

My reloads are coming out just about like yours .373-.374 and that's with mostly Rem. brass.

That's from a standard Lee die and I don't have any problem even in one of my AR's that has a .223 chambered Bull barrel. The only thing I have to watch on that is OAL because it has a short throat.

It does sound like the small base die might help you.

Boxer on that drawing it says that the .3769" measurement is + .002". do they mean the minimum is .3749" if that is the case then your chamber sounds like it maybe undersized for a milspec 5.56 chamber.

Minimum saami:

That is the way I'm reading it too.... I'm giving the manufacturer a call this afternoon to confirm.
I'd rather not run a SB die if possible that they could ream the chamber up a bit. Maybe to .375

I've run SB RCBS dies since the early '70's, first for the AR I had back then and ever since for my bold Sako. I've never noticed any problem what so ever loading with SB but I only use military brass so perhaps that makes a difference. Simply don't know.

I would expect an ID dimension to have a positive tolerance (+0.002") because a larger ID wouldn't prevent something from chambering and an OD dimension to have a negative tolerance (-0.006") for the same reason. Both tolerances are spec'd as "unless otherwise specified".

So, the 0.3769" ID would have an upper limit of 0.3789". It it didn't work this way, a proper sized round (0.3759") wouldn't fit in the 0.3749" chamber.

I tend to agree that is how it could be interpreted. But it states that the measurement of .3769" is a plus .002" unless otherwise stated. which seems that it could mean the minimum would be less. And that is what Boxer seems to be running into.

Or it could be that we have discovered who really makes the barrels for LWD.

I agree that the data points to this... I also confirmed that my Dillon case gauge which I know is MAX SAMMI is indeed .380
I just called the manufacturer and he is gonna confirm my numbers against the drawings they have for the barrel chamber.
I still suspect that they my rifle didn't get a final reaming.

The proper way to interpret that chamber tolerance is to take the specified value and add the tolerance.

0.3769" +0.002", -0.000" so the dimension can range from 0.3769" to 0.3789"

For the cartridge, the spec if 0.3759" +0.000", -0.006" so the dimension can range from 0.3699" to 0.3759".

Regardless of which direction the tolerance stack up on the ID or OD, there will always be a minimum of 0.001" of clearance. Of course, it could be as much as 0.009"

So the minimum chamber diameter in that instance would be .3769". In which there does seem to be a big discrepancy between the minimum and Boxer's chamber if he is having the problems of sticking cases or a huge expansion of his cases. (doubtful). Luckily Ranier warrant's their barrels unlike some others.
