Stepped forming bushings.

Who knows where to buy stepped down neck-sizing/case-forming dies? I form 7mm from 30 brass, 6mm from 6.5 and .22 from 6mm and in each case I'm unhappy with the results when using normal forming methods.


I talked Neil Jones into making a stepped neck forming bushing for my latest project but he fought me on it. (I've gotten two stepped bushing setups from Neil but in each case he doesn't prefer doing it.)

My next project will include making .30 from .338 using very heavy brass........

Below are some pictures from the "Al's 6X47L" thread, same set of pix, pictures showing improperly formed and properly formed cases. I'm going to be needing some more dies for this sort of work.

I don't need the dies to be hardened but I DO need the step in the neck so that it forms like these pictures. (Or wherever I spec it, some will be in the case body for other projects)

First picture shows the problem, look at the second and third cases, the middle cases.

Last three pix are the beayooootiful results achieved via a stepped neck die.


help!

Al, try Butch Lambert - I believe he makes a very nice set: http://www.shadetreeea.com/ Good shootin'!

Randy, the problem is the step inside the neck bushing. Butch MIGHT do it, dunno.

Most folks just want to argue about it.

One die maker would do it for between $800-1000.00 but said it was "the stupidest idea he'd ever heard. He's been making 6X47L cases with standard bushings and they shoot great, straighten right out".... etc, etc.

I don't want the argument, just CAN or WILL anyone do it?

I'd be happy with stepped Wilson/Redding style buttons/bushings..... in fact this would be BESTEST of all......

Edited for clarity...

In all fairness, the die maker who wanted to charge 800-1000 was providing an entire hardened FL die with 3 bushings. Not that this is in any way acceptable, but it was for a complete fitted die set..... not just some stepped bushings :)

I just received some 6X47 Ruag Swiss Match brass today.It is once fired brass from a factory chamber and just in front of the base measures 0.4752 inches.The guy who sent it has 1200 pieces but didn't like it because it fit tight in his chamber.I think he was using a 308 small base die to help alleviate the problem but wasn't satisfied with the results.
I am thinking very hard on using your larger base approach to check concentricity as it is very easy to see on these cases.
I know nothing could be this easy but it appears one could run a 6X47SM reamer into an old 6BR barrel without having too worry about a bulge forming near the 6BR's shoulder.It could be a good use for the old 6BR barrels.

Just use your 6BR reamer if the shoulder's big enough. The 6X47L barrel I'm shooting now was chambered using one of my 6BR reamers run deep. My newest reamer is set up for both 6X47L and 6BR. The only thing to know is that the neck on the 6X47L wants to be 40thou shorter than the 6BR. I'm chambering my next 6BR using the 6X47L reamer. I'll just trim the necks back.
