Problems with calibrating (FL sizing) the base of the 223REM Lapua brass 6× and 15× fired

[Rio Precision Gunworks]

worst maker? ask people, how to get consistent primer depth with overpriced 1000$ piece of shit CPS and lee 100$ ACP ...

polishing and cleaning are... different things? in tumbler? wet tumbler? ultrasonic? NO!
with those things when you ''clean'' your brass, you are also polishing it!
use wet cloth and you wont polish your brass when you will clean it. I dont clean (and polish) my brass because there is nothing to clean...

You can't polish brass in an ultrasonic. LOL. (well, you can, but it takes an exponentially longer time and different chemicals. and the polish isn't what most people would consider polished).

Hence why a second type of machine is needed to actually polish the brass if you'd like it to not be dull. Some processes do both clean and polish, while others may do one or the other. Ultrasonic cleaners will leave the brass looking very dull and at times tarnished.

You'll need something like stainless pins or dry media to polish. Much like you'd need a pad and your elbow to polish brass by hand. Just like taking a rag with or without a cleaning compound and wiping your brass off would only clean the brass and not polish it.

You've also talked yourself into a hole here.

You have determined it isn't, and insulted people who have suggested needing to clean your die because you don't clean your brass......and that it's overpressure and expanding your case head.

So, the only thing left at this point is that your chamber is allowing more expansion than your die can size.

you dont know how to use QL, and you dont know my dimensions of loaded round nor long freebore.

Maybe but I know you're retarded. You're the one having problems and asking the people you called stupid for help.

So cleaning brass helps to keep your dies clean. And prevents stuck cases.

Regarding your base dimensions, measure the base before and after sizing before we continue this conversation.

tommorow I will sizing brass in other box, but the same LOT of brass and same number of firings. I will see how it goes.
After that, I also have new, 1× fired Lapua brass, and I will see how sizing proces will go with this brass. But I dont expect any problems with new brass.

I cant accuratly measure the base because this is not an easy process. I dont have micrometer for 0.0001' measurement, and also I dont have any tool that I can measure the base at EXACTLY SAME SPOT every time.
measurements with caliper are inaccurate and always at different location. And if I measure the bottom of the brass, this measurement means nothing because this is unsuported and unsized portion of the brass...

Put the brass lengthwise in the caliper jaws. They will measure the fattest point that way. You don’t need to measure to the .0001”, just to see if you have enough clearance after sizing, like .002” or so.

Guess what this is? Clean brass that goes into a clean die. They gets resized just fine lol.

 

[MarkyMark007]

ok, I measured accuratly as I could with ordinary caliper, and at 0.380'' height from the bottom of the brass, the difference of diameter between fired and sized brass is 0.0025'' to 0.003''.

So back to square one… clean your brass in a vibratory tumbler with dry media and some polish compound in it. Comes as a pretty affordable kit like I posted earlier. And service / inspect your die.

OK, then problem solved. Now clean out the die and and should be gtg.

That has got to be the most ratchet looking brass I have ever seen- outside of brass that somebody left on the range for several months in the elements. That it sizes well when polished is telling you something. Maybe try cleaning your brass

Cleaning brass is a myth.

You didn’t get the memo?

 

[MarkyMark007]

Where is the spot on the brass where it's getting stuck on the die?

it's hard to tell, but I will try to find that spot. But maybe it will be next month, because I dont know when I will fire that problematic brass.

OK, then problem solved. Now clean out the die and and should be gtg.

so 0.003'' diffrence in diameter is normal?

clean your brass in a vibratory tumbler with dry media and some polish compound in it

I promise that I will try to do that. At friend. I ony have ultrasonic cleaner, so maybe this will give me some early answers.

I have the same looking brass in my 284WIN, and in 8× firing it is normaly sizing. But in Redding die, not Whidden.

Also, do you own another 223 sizing die?

I think I have Lee FL die, but I drilled out the hole so I made shitty 'body' die out of it.
And now I use it like a mandrel; instead of decaping pin and expander ball I put inside custom made mandrell.

 

[918v]

so 0.003'' diffrence in diameter is normal?

Yes 2-3 thou is normal.

Do you want less clearance?

 

[MarkyMark007]

here are pictures of sized Lapua brass, 6× fired, from another box but same LOT as other problematic 6× fired brass:

2× upper pictures of uncleaned sized brass with Whidden bushing FL die.

it is clear that Whidden die leaves bigger mark on the brass than Lee die, and sizing with Lee die is easier than with Whidden die.

But it is easier sizing when brass is cleaned with ultrasonic cleaner. So I guess I will clean my brass every year after season but I wont clean necks, because I leave carbon residue for better friction and constant neck tension.

But when I measure diameter of sized brass when sized wit Whidden versus Lee die, in the middle of the bright portion was the same diameter when sized with Whidden or with Lee !!
So I guess something is wrong with the bottom of the Whidden die, so I will try to polish it very well. maybe there is some untracable ring in the bottom of the die...

 

[Rio Precision Gunworks]

Both dies appear to be sizing down to the .200 mark just form looking at the pics. How much sizing, you'll have to measure.

It could be from the inside of the die, or just something in the lighting/angle of the pics. But I'd take a look and check the pieces on the right to make sure you don't have some impending case head separation.

 

[MarkyMark007]

those marks were made by me at 0.262'' height (in the middle of Whidden 'section' 'mark'), for 'accurate' measurement of diameter of both brass.

 

[918v]

I see what’s happening now. Your Whidden die is pushing the brass down, forming a belt of sorts towards the bottom of the case. And it is scratching up the brass. Send the die back with a few cases and tell them to polish the inside.

If not, then you clean the die real good and size the brass with some good lube, like imperial wax, and see if it persist.

Op must be just fucking with us….

Amazon product ASIN B000TTILBC
This, and polishing your die if still serviceable should do it.

you're a shill for amazon
