30 Carbine Rapid Trim Die

Any chance of a 30 carbine rapid trim die for the 1200 rapid trimmer?

We have tried, but the cartridge is too short- the exhaust hole in the die for the vacuum to suck out brass chips is buried in the toolhead. If you really want one, go to www.ch4d.com- they will make a custom trim die in pretty much any caliber.

Did buried down in the tool head pose any real problems?

I'm not opposed to a little modification.

Without being able to remove the brass trimmings, they quickly wrapped around the shaft of the motor and bound it up. You could use one on a single stage if you machined the head of the frame thinner.

What your thought on milling down an old tool head for a 1050? Just one or two stations, enough to clear the trimmer.

You could probably use an endmill or keyway cutter to thin an area around the toolhead for clearing the vacuum manifold. Wouldn't pose any structural issues.

I keep a RCB electric timmer bolted to the bench dedicated to .30 carbine and my Dillon is dedicated to .223, works for me.

RE: 30 Carbine Rapid Trim Die

I just built my own trim die for my 30 carbine brass for use with my Dillon rt1200.

I cut off the top of a rcbs die about 1/16" from the fully extended brass.

One needs to lathe the face to insure it's true for alignment to the trimmer. Using a 6" Long nipple 1/2 schedule 40 I threaded the pipe to match the RT1200 coupler. It's an archaic thread like 13/16x20....

I also drilled a hole through the pipe for the chip removal. After touring both the pipe and die mating surfaces and checking clearances the two pieces were welded togather using my miller tig machine.

You must use a die to grip the brass or it will spin.

I am pleased now to be able to size and trim each piece of brass to a tolerance of 0.001" at a rate of 6 cases per minute.

I did have to mount the whole set up on a rcbs 50 bmg press, which surprisingly has the thinnest top head. Still, the bottom ram had to have an adapter under the shell holder to push the brass deep enough into the top head to exceed the die for cutting. I'm not sure it can be done on a Dillon even if you do mill the die holders. I thought of doing that but it appeared I still wouldn't have the clearances needed.

Someone needs to make a press just to decap, swage, trim, and chamfer a rifle case. I can do everything g but chamfer on my 1050 with my rt1200 but for high accuracy chamfer is critical to not scrape the jacket to damage the concentric weight distribution for longer shots.
