Reloading question SOLVED THREAD CLOSED

[Rerunner]

I have Hornady .40 pistol dies on my dillon 750. Resizing die is fine. Have dillon powder die with appropriate flare. I inserted the hornady bullet seating and crimp die. Here it is: I insert a flared case on shell plate and thread the die body until resistance. However I do not touch resistance. The die body threads until contact with the shell plate. So, I then put a flared case into the shell plate, placed a bullet on shell and lower the ram then I thread the bullet seater top until it contacts the bullet. Success. I am able to achieve my OAL. However there remains a flare on the brass. Achieving OAL is not issue. I cannot reduce the flare remaining. More interesting, I pulled a bullet and there was a indented mark on the bullet from a crimp BUT the flare remained!!!!!!

flared case in shell plate AND resized but no flare are placed in shell plate and when the ram is lowered I thread the die body, feel no resistance and until it touches the shell plate. I called hornady. Only solution is my .40 brass is short but ALL MY BRASS IS SHORT? i ordered a new set of dillon dies and ready to toss these hornady.
But I appreciate anyone's thoughts.

I don’t see mention of a crimping die… the crimp die is what removes the flare and applies a slight crimp to the neck.

The dies are from Hornady item# 546533. One resize die, one expander die (not using due to powder die from dillon), bullet seater and crimp die all in one die. According to Hornady and instructions.

Found the solution. The Hornady die set was a 3 die set. The bullet seating and crimp die is a roll crimp. I need a taper crimp die set. Additional $50 give or take. The instruction manual mentions nothing about this crimp die being a dedicated roll crimp die. I had to dig through the internet due to my foreign information with Hornady.

I doubt that's correct.
I have never heard of any reloading die maker providing roll crimp dies for cartridges that headspace on the case mouth such as 9mm/40/10/45acp as all of those cases need the belling removed and the case pushed back against the bullet in order to fit into the gun correctly.
Call Hornady and see what's really up.
Most likely, you need to move the locknut to the bottom of the toolhead to get the die body further down to actually get some proper taper crimping.
The dillon dies will have separate seating and crimping dies which will work better than trying to do both those steps in a single die.

Lee factory crimp die does this, all day long. But, if improperly adjusted, it will create a round that is "headspace challenged".

Most seating dies will give a roll crimp, and will work fine if adjusted right. In fact in the early days the roll crimp was preferred. I use a separate lee taper crimp die, I feel like it gives a perfect crimp, I like .468.

This is from a NRA handloaders guide from the late 60's.

Things have changed since the 1960's.

[Sandspider500]

Yes, but the die can be set to take the flare off the case. It doesn't have to be used as described in that old pamphlet.

[Rerunner]

Gentlemen, I appreciate all the feedback. Hornady sells a roll crimp die separate from taper and bullet seating die. Some of our old ways have not caught up to technology. The Hornady taper / seating die is twice the length of any other die. Appears as tall as a Forester micrometer die.

Really (?).

"Things have changed since the 1960's"

For smokess powder cartridges?...Not that much... But ymmv.

[the_tunaman]

Seems to me a roll crimp inserted by the seating die wouldn’t fully address the flare and might leave a slight ridge?

Came across some old RCBS 45 ACP "roll crimp" die set.....but those were a 50 year old set from the early 70's, probably for the WW 1 and 2 revolvers....But nothing modern would make sense.
