Tired of having the taper erased from your .30 Carbine brass?

The taper doesn't get "erased" by carbide sizer dies. Been using Redding, I think, for 40 years. However, the brand of die doesn't make much difference.
That single Lee die is almost as expensive as a whole Lee set including the carbide sizer die from Midway. Same price for just the carbide sizer though.

Wanna bet? That's why Redding introduced their Dual Ring Carbide Sizer Die.

Redding has solved the problem that has plagued ordinary carbide dies since their invention. The little ring in a standard carbide die had to do double duty. It sized the top of the case to properly hold the bullet but then continued to size the whole body of the case as well. Unfortunately, these two areas need to be sized at different diameters, so carbide dies of the past have always been a compromise.

A carbide single ring die sizes the whole case to a uniform diameter down to where the ring ends. That Lee die, however, appears to be a full-length solid carbide die with the same profile as a steel die. Such dies normally need lubrication, as you are making contact between the case and die down the whole resized length of the case. You don't need lube with the carbide ring dies because they make contact with only a short part of the case length at a time, reducing friction.
 
Is that the reason you never see carbide rifle dies? While technically possible to mill, you would still need lube since the contact area with the case is so great so they just stick with steel?
 
Yes , normally there is one carbide ring , works just fine on straight sided cases.
Tapered and bottle neck rounds don't work as well.
My 9 mm Lee Carbide die takes out the taper....sorta works , but my old CH4D steel dies put the taper back in and works so much better.

I would call Lee and ask...I would bet Lee has only one carbide ring ...their ads and catalog don't say anything about two rings.
The 30 M1 is tapered , from.356 at the base to .336 at the mouth so it has a .020 taper to the case.

Personally, I think it's a bit of advertising "fluff" by the Amazon seller, with no basis in reality. I think it's nothing more than the standard carbide resizing die used in Lee's .30 Carbine carbide die set. Buyer beware.

USSR,

So your contention is that Lee is using a carbide ring like everyone else and the "full size" claim is a lie. Correct?

I'll call tomorrow and ask directly:

  1. Are you using a carbide ring like everyone else?
  2. Or are you truly offering a carbide sleeve the full length of the case? And if so, is the carbide sleeve tapered to match the SAAMI specs of the case?
Should that do it guys?

Personally, you are wrong. I just examined by Lee .30 Carbine full-length carbide sizing die and it has a carbide sleeve that, if it is not full-length, is nearly so. I have been using it for several years now and it works well...does not ruin the taper, but need some lube.

Lee has been selling a full-length carbide die for some years now. It has nothing to do with the brand...it has to do with whether or not it uses a carbide ring or a longer carbide insert.

The full-length carbide die (full-length tapered carbide "sleeve")is logically more expensive than a die with just a carbide ring.
 
Haven't looked at a .30 carbine die.
9mm P has a good deal of taper for a pistol cartridge. The better dies have longer inserts so as to not wipe out the taper.

Dillon sells full carbide .223 and .308 sizers. Lube required, the purpose is long life in commercial Reloading.

That, and whether it is the same carbide resizing die that is used in their carbide .30 Carbine die set. I've got their carbide die set, and there is nothing special about that resizing die. Thanks jski.

With a long, tapered case like the .30 Carbine, it's easy to see if the resizing die is sizing in a tapered way or not; it's called "wasp waist".

Guys,

Let me show you what I got from the Mercedes of reloading equipment ... Dillon. Here's a Starline .30 Carbine case after resizing it with Dillon's carbide die. Check out the "belt" at the bottom. About 1/3 of my Carbine brass ended up this ways.

I think we can safely conclude that the vaunted Dillon uses carbide rings vs. carbide sleeves.

Yep, it sure is ugly. You'd think Dillon could do better? Their quality engineer has emailed me asking for me to send him new Starline .30 Carbine brass. Shouldn't Dillon be able to afford new brass?
 
The Lee 30 carbine die has carbide ring of 3/4” long, which is shorter than the brass. The sized brass will have taper approximately 3/4" from the web and then straight wall to the mouth, just like in the posted picture.

It is not quite like in the official drawings of the casing, but probably within it's tolerance. It doesn't harm anything anyway. I have used that die set for years.

BTW it really doesn't need lube.

Correction. The carbide ring is 1" long rather. But it is still shorter than the brass.

Just spoke to a Lee quality engineer. He told me their “full length carbide” dies have a carbide sleeve the full length of the case (minus the rim) and are tapered to SAAMI specs. The same for all tapered straight walled cases, e.g., .30 Carbine, 9mm.

So yes, they’re the only ones with a carbide die that doesn’t erase the taper.

It is close but not 100%. In the case of 30 carbine, the last 1/8" or so is not covered. But it is mighty good enough. The bullet will make that section straight anyway. There is really no need to worry about it.
