380set back

[gnostic]

Country-Gent has it right. My 380 dies really size my brass down small. My loaded rounds have a coke bottle shape and a little taper crimp, finishes them up...

Dougguy I already knew I lacked neck tension and need a smaller sizing die.
Initially misread your original post as the issue was 'Not neck tension) and was just tying to explain my reasoning to you.

Outpost75 you do have a point on the differing brass thickness and springback.
I currently have 3 9mm/380 expander/powder funnels, .357", .354" .353"

But if I can seat a .355" bullet in a sized case without expanding it at all and without swaging down the bullet my first issue is with my sizing my cases.

Feedback from my other thread and some PM's shows that I am not the only one that has issues with an Oversize LEE sizing die and their lack of support.

That is what I meant by this comment.

It matters that your bullets are too small for your cases and there is no tension or the cases are too large for the bullets and there is no tension.

Once you find a resizing/decapping die that works well for you I think you will be in business. I have taken to just making an expander plug for whatever boolit size I am loading until the tension feels about right at the press.

I have a new project starting with .45 Schofield brass, and haven't yet even sized the first case or loaded the first round. SAAMI calls for a .454" boolit and I have .45 ACP, .45 Colt, and .45 Schofield die sets so I probably have enough variance in those to figure out which one is going to size correctly for .452" boolits. I am sure there will be different case tension with each die. I don't know if Lee made .45 Schofield die sets based on the SAAMI spec for .454" boolits or made them to use .452" but we will soon find out.

You are correct here. Like I mentioned earlier I would've already bought a 2nd kit and seen if I had the same issue. Mail it back to Amazon for a refund if it didn't fix it. I didn't know there was a difference at first....so assuming I had a lee turret press I needed lee dies.

Sigh, apparently I should've done more research. I'm now having the same issue with factory jacketed bullets vs my home cast loads. Little to no neck tension on the hornady xtp 90gr loads. I'll be ordering an undersize die for loading jacketed as well and hopefully it will fix my issue. I switched back to loading cast bullets and had no issues.
