45 Colt Brass Thickness

Could anyone measure the thickness of a few pieces of other than Winchester brass? the batch of W-W I have measures 0.0115".

I recently began loading 45 Colt using 250 RNFP sized to .452. I learned the sizer die did not size the brass sufficiently, leaving me with zero neck tension. I called the die manufacturer and spoke with a tech rep. He told me they had changed the sizer because of cowboy shooters complaining about coke bottle cases. He said he would ship me a different die.

Fast forward several weeks and no die, so I call again. Tech rep tells me my brass is too thin and there is no "different die."

I may have to stick with the .45ACP die. If that's the case, I'll return the Colt die set and purchase a seater only.

Thanks for any help.

Same for me on Winchester .45 Colt brass, give or take .0002, best I can tell.

Hokay. Using my simple dial micrometer, I have measured a sampling of ten cases of each headstamp, as follows:

Winchester @ .0110
W-W @ .0110
Starline @ .0110
FC @ .0110
Hornady @ .0100
R-P @ .0090

These case have been loaded twice, and were measured after resizing. I use a Lee die set and MBC bullets sized to .452 with zero issues.

Thanks, gentlemen. I'll be calling Hornady again on Monday.

Worst case, you can use a .45 ACP or a .30-06 (or .308 or .270 or...) die to "neck size" the .45 Colt brass. They will end up looking like .44-40 cartridges.

Fired and unsized Top Brass. .009 average.

Winchester @ .110


I always heard everything was bigger in Texas! :D

Take it clear out and see what you got.

If the case measures .450" or less after sizing, but before expanding & belling, you just need to turn down the expander a few thousandths.

Hornady expanders are one piece and I don't have tool capable of measuring it. Cases sized with an ACP die load fine using the .45 Colt expander. A sized case from the Colt die can be insert in the expander die by hand.

The TiNi insert measures 0.471". Looking at the numbers above and taking springback into consideration, this die wouldn't work for any of the brass mentioned.

I think the sizer is designed for the older 0.454 guns.

You might try RCBS dies.

The standard die set is for modern .45 Colt with .452" jacketed or lead bullets.

The "Cowboy" die set is for .454" lead loads.

If I get a negative response from Hornady, I'll return their dies and more on to something else.

Eddie, I can't speak about any other dies except RCBS's as that's the only ones I currently have and use. However, just FYI, I shoot the 45 ACP and the 45 LC and have nothing but good results from the RCBS carbide die sets (.452 lead/.451 jackets). I shoot jacketed and cast lead in both... Hope you get it figured out amigo.

As I was reassembling the size die I noticed the decapper stem looked "odd." Then the light came on; it's for a .308.

Must have been made on Monday or Friday.

Contacted Hornady today and spoke with a different tech. He verified my measurement of the sizer insert (0,471") and said it was indeed for .454 sized bullets. He said they send out a .454 Casull die which measures 0.469".

I guess he has been keeping this from the other techs.

Hopefully, third time is a charm.
