Thats what I was trying to see on Jackies jacket but photo is a little dark. You are correct it is a thin section from the drawing process. I would say from to much reduction on the last draw...
The results look good. But the one the matters is the paper test. I know your going to share.I lubed up 350 30 caliber cores exactly the same way I did the 6mm and core seated the jackets yesterday evening.
I just pointed them up this afternoon.
Just like the 6mm, they came out .0002 larger on the shank than the squeaky clean cores.
They went in the die find, no different than before. But the extraction stroke was definitely more difficult. Almost aggravatingly difficult. I even stopped after a few and re lubed them, adding about 2 more grains of lube. Nothing changed.View attachment 1658971View attachment 1658972View attachment 1658973View attachment 1658974
You can see from the two sectioned bullets that the core did progress further up in the jacket. The one on the right is the lubed core bullet.
One other thing. The lubed bullets have a faint shadowy ring just above the base. I don’t know what that is all about. The base is about .0002 larger than the shank.
I don’t wish to be pessimistic, but that ring just above the base bothers me. It’s the first time I have seen it on our bullets.
I’ll test them Sunday.
Of course, the first question should be……Who or what company made them?This might not be the best place to ask this, but I think there is more bullet making knowledge in this thread than anywhere else I know of, so...
I have attached a couple of pictures of bullets to this post that have some pretty awful looking 'folds' in the jacket. These are from a major manufacturer. I found 5 similar to this in the last 80 or so rounds I have loaded up.
I have a few questions for all the bullet makers here;
1. What causes this?
2. Is it a problem that will show up on target?
3. Should I shoot them?
4. Should I contact the manufacturer?
5. Should I ditch the entire lot of bullets (based on the number found so far)?
Thank you in advance for furthering my education!!!

this usually comes from a crooked pinch trim but a really soft jacket can also be the cause, I would venture to say its probably the first oneThis might not be the best place to ask this, but I think there is more bullet making knowledge in this thread than anywhere else I know of, so...

The lube part of bullet making is critical. Quite a few different recipes work but they all share some common traits. As strange as it sounds, jacket lube can be too 'slippery'...it needs a certain amount of drag. Randy Robinett says it best...lube is a necessary evil.A wise man said to me, it's all about lube control on making great bullets.
Maybe ask Han SoloI got this yesterday. I wonder if Charlie could do anything with this for cores????

Maybe Princess Leia.....Maybe ask Han Solo
Now that is high teckIt's a cool, windy, rainy day here in The Forbidden Zone....good time to seat cores. They get pushed down using this trick C.S.D.'er (Core Stuff'er Down'er) tool, courtesy of the Hu Hot Mongolian grill.
