30 TCU

Postby ihmsa-2116 » Fri Nov 18, 2011 7:51 pm

Does anyone know if the 30 TCU dies are still made? It's the 7mm TCU necked up to .308?

Or does anyone have a set of these dies they would like to sell?

I have an email out to the die companies and waiting to hear what they have to say.

thanks,

Harry

There is a listing for a 30 T/C full length dies set (part # 25201) at http://www.huntingtons.com/ref_diegroups.pdf

Ah ! Therein lies the problem. The 30 T/C is not the same as the 30 TCU. The 30 T/C is some "all powerful" cartridge that T/C developed for their rifles.

It's 30 caliber all right but way too big!

Still "In Search Of"


I have an extra set of 7 TCU dies. I should just see if someone could open them up to 308.

Harry - Saw this old post and don't know if you ever found your 30 TCU dies but go to ch4d.com and you will find their item number DS30-223Rem which the 223 necked up to 30 caliber which I believe is the exact same as the 30 TCU. If they are not exactly the same, it will just be a few degrees difference on the shoulder and I bet you could adjust the dies enough to make them work to form the brass then back them off about .020 and just use them to neck size after you have fire formed the brass. I bought some 30BR dies off them and they are great. They are located in Mount Vernon, OH and their prices are very reasonable.

I agree on the CH dies. I live about 20 miles from them and they are great to deal with.

Thanks guys,

I've communicated with CH4D a couple of times and still haven't decided how to proceed. Through a lot of testing, I've discovered that I can use a 7tcu redding bushing sizing die I have to deprime/size the brass and a 300 Whisper die to seat bullets if need be. CH has several .223 dies but they don't know a lot about them. All they know is that the dies in their catalog are dies that customers have ordered in the past. They don't know what a TCU cartridge is and suggested I wanted the 30-223 with with the 23 degree shoulder as it was the "most popular". I'm not positive but I believe Shilen chambers their barrels in the TCU shoulder of 40 degrees. Ch says that is an "Ackley" cartridge and their "second most popular" 30-223 die.

I also emailed JL Precision who converts full length sizing dies into full length body and neck sizing bushing dies. JL says he can make a 30 TCU die out of a standard 7 TCU full length sizing die for somewhere around $85 or so and I think I may go with this option. I've gone this route with him once before when I had a FL RCBS 30H die converted to a bushing neck sizing and full length body sizing die. I just didn't suspect he could make the .30 from a 7mm. I think this is the best route to take.

thanks again,

While I haven't gotten dies, I can reload as I described in my above reply. If you wanted dies, I believe the CH4D company can supply dies assuming you know what shoulder angle you need. I still have not done a cast of my barrels chamber so I don't positively know what the shoulder angle is. I believe it is the 40 degree shoulder just like the 7 TCU. That isn't 100% for sure though because some books list the 6 TCU as having a 23 degree shoulder like the original case the .223 and I always thought that was also 40 degrees. There isn't a whole lot of information on this round on the net. At least I haven't been able to fine a lot searching.

I do believe several articles were written in magazines back in the '80s but I saved very few of my old magazines.

The round is just the .223 case opened up to take .308 bullets.

That's my story and I'm sticking to it.

It sounds to be an interesting round. Lot more 30 cal bullets to choose from and .223 cases are still pleantfull.
If you do any chorno test would love to see them Please.
