Ohhhh....kayyy. Help? (Pic)

Here's a new one on me. Have used 75 Amax's previously a bit, but only moly coated. Look at the case shoulder...wait, what do you mean there is no shoulder?

Let me guess, lube the inside of the case mouth?

I have done that with Lee dies set too deep.

Adjust the seating die properly,

The only time I've had anything remotely similar to that happen was from trying to crimp too much.

Are the cases collapsing when the bullets are being seated? Is the case mouth contacting the crimping shoulder? Perhaps the necks are too small.
Were you using a smaller expander button when setting the cases up for moly'd bullets?

 

[Redhouse]

Not crimping. It's happening during the seating process - the shoulder is folding on the press stroke. OAL is correct, not sure what I need to adjust on the die.

I neck sized using the same neck sizing die as I've used on my prior 150 or so loads (I'm new at this), no prior issues.

Never mind, I figgered it out. This teaches me to go not do this when I'm this tired, lol. Had the die too far down, as you were trying to tell me above.

Redhouse Improved?

Nice looking shoulder though. Get a reamer made, call it a Redhouse improved.
