after fullsize - "ring" at the bottom

[nidm]

hi, folk,

is this normal? this is 308 after full size. thanks

[highpower790]

Perfectly normal.

[J-cat]

I concur

[MarikinaMan]

I recommend testing them with the pin thing just to be sure.

But I will get those too as that section is where the brass is worked a lot.

[nidm]

folks,

thanks for the quick responds. so I won't worry too much.

BTW, I did the "pin-test" with the dental tool as MarikinaMan suggested above, and feel the brass is OK.

Yes that is normal. Actually, the die looks like it is contacting a major portion of the case. That is good if you want to return the case to more of a SAAMI Standard. Otherwise, working the neck and shoulder to a lesser degree could provide results more favorable to better accuracy. It really depends on what gun and for what use you intend for your reloads.

I got that when i switched from my lee carbide 9mm sizing die to the undersized sizing die

[M1NM]

Why undersized die? Normal should be fine. The ring looks a little tall. Is your die set all the way down against the shell holder? I run mine down until it touches then give it a little more so you can feel the handle has a little cam over feel.

OP, your cases are good. Normal and no worries.

Not enough time in the food dehydrator?

What does this mean?

Your shell holder has a deck height of .125" meaning the shell holder is not involved in sizing the case. Not all of the die is involved in sizing the case meaning the base of the die is larger in diameter then the base of the case. I have suggested the reloader turn the case around and stick the case head into the die. That would require the reloader to remove his hands from the key board or out of his pockets.

Anyhow I have reversed cases and shoved them into the die; as a rule all of the case heads fit into the open end of the die with very few exceptions, and for that I do not believe I will live long enough to explain what all that means.

Reloaders have gigs and gigs of space used up when talking about small base dies or the need for small base dies. I know no one want to hear about my small base die but I am the only reloaders with small base dies and I am the only one that can measure the base of the die for 'shortness'.

More like headcase separation,
OR more accurately case-head seperation...

Typically, I see case head separation occur if you sized cases with more than 0.005" shoulder bump.

In my early days of reloading, I did a whole batch of 6.5 creedmoor. I was getting case head separation on every shot. I packed up, went home, pulled a bullet and found that I had sized the cases with 0.007-0.008" shoulder bump. My setscrew on my die was not locked down There went 90+ cases and pulling the bullets and powder was not fun.

and then;

Because you are on the 'U.S. RIFLE TEAM' I believe I am allowed to disagree with you. If the locking nut gets loose and the die backs out the distance between the shoulder and case head increases. When that happens clearance is increased. As you should know I am the one that cannot move the shoulder back when sizing a case with a die that has full body support. I am the fan of off setting the length of the chamber with the length of the case.
