Carbide die for straight cased rifles?

[P.A. Myers]

 Does anybody have a carbide die available for 45/70? 375win? 405win? I would need only the sizing die obviously. Could a carbide die for another cartridge be modified to work? I have often wondered why I have never seen carbide dies for straight cased rifles.

tapered cases no can do. you may get buy with neck sizer only, maybe not

True on the tapered cases, but i do have carbide dies for my 357 Max carbine!

I have used my 45 Colt carbide sizer to neck size 45/70,  then flair the mouth and go on as nothing was different.

Lee makes a carbide die for the 30 carbine, it says to use lube in the paperwork. Thick wall cases need lube.

9mm parabellum is a tapered case. Just as tapered in it's short length as those "straight walled" rifle cases. I always wondered how that worked. I notice it undersizes the brass near the base/rim. Some one could make a carbide sizer with a second, smaller diameter ring further up inside the die to get the mouth smaller than the middle and the base. Why doesn't someone do it and patent it? I would if I had the funding. Any backers?

Dear Flash, good idea I'll do it

I'm gonna try that myself.

One of the reasons carbide pistol dies do not require case lube is because of the relatively small surface area of the carbide sizing ring that engages the case wall. The small area reduces friction to allow lubeless resizing. A second sizing ring might create sufficient friction to require lubrication.

Dillon makes carbide sizing dies for 308 & 223 at least, but they require lubrication. Their main advantage is long service life in semi-commercial reloading operations.

I've got a set of those.  I didn't read the directions.  I also didn't stick any cases without lube, but they were extremely difficult to run through.  Just a little lube helped tremendously.  If I'd have known that I was going to have to lube cases anyway, I probably would have just bought steel dies anyway.  Oh, well.

I somehow ended up with two sets of 30carbine rcbs carbide dies. I've never used them. I have seen recently titanium-carbide sizers. I always wondered if dimpleing in these straight[tapered] cases could be prevented by venting of some kind. Holes, grooves, rings?

the only thing carbide on the dillon 223 and 308 dies is the expander ball. It is done to make progressive loading smoother.

Carbide Dies in a 9mm are hard to size with the small short tapered case.  I had carbide dies for my Star Progressive reloader.  I had to lube about every other case just to make it a smooth operation, so, that is so much trouble that I just lubed them all anyway.  The carbide was a waste of money and as much effort as steel dies.

I'm sure that all Rifle "Straight Walls" are not cylinders.  They are Tapered for ease of extraction after firing in the chamber.  

However, the black powder crowd do get custom made Neck Sizing dies for all 45s, 38s and 35s.  I don't know exactly where they get them, but I was a spotter for 5 years and ran with the crowd. Didn't shoot that stinking sulfur, but I was in on their conversations with first hand knowledge.

One member mentioned the Carbide for the 357 Maximum. That is a true straight wall case.  It is just a little longer case than the 357 Magnum and nothing more.  Love that cartridge, though.

I have worked with 45-70s, 38-55s and the various 35 Maynards and etc..  They all require lube for full length sizing.  Carbide dies will require lubing the cases, as well.

My 444 Marlin cases are tapered as well.  I full length size the cases with the die backed off just enough so that the neck of the case works with the expander die and still holds the bullet firmly.  The cases fit in my Marlin just fine.  (Who says that "Micro-grooved Marlins don't shoot well?")
