Title: What does your sizing die size down to?
Post by: alank2 on July 29 2012 05:28:27 PM MDT
Hi,

I have a Redding Pro series TiC die that sizes to 0.4165 to 0.417 and a Lee carbide die that sizes to 0.418.  Out of curiosity what does your die size brass to?

Thanks,

Alan

If you're measuring at the middle of the case, my LEE carbide dies put new Starline cases right at .416". Hope that helps.

Hi,

Yes that is where I am measuring at - thanks for the measurement.

Starline cases with Hornady die 0.419". Mines bigger.. :P Just kidding, but that is the measurement.

I was prompted to ask because of the 10mm reloading issues I ran into, see my thread at another forum for creased cases and a mid case vertical split in brand new starline nickel brass using a mid power level load.

I am surprised that there isn't more consistency to this, you would think there would be an ideal size and that manufacturers would stick to that.

I've never had these types of problems with any other cartridge I've loaded before (even when I loaded 10mm before a few years ago)...  I'm swapping the nickel for some regular brass with Starline and I'm changing my reloading plan to lee bulge bust a fired case and then only sizing the case area where bullet tension is needed.

Thanks,

Alan

Seems Redding is in the process of solving that issue with their new (as of 2011) patented Dual Ring Carbide Sizing Dies.

They say;  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.  Redding's solution to this problem is a unique (patent pending) design, incorporating two carbide rings within one sizing die. The upper ring is positioned to size only the bullet retention portion of the case while the other is located to properly size the case body without overworking the brass. Sized cases will not only look and function better but brass life will increase.

The only thing that sucks at this time is that they aren't yet available for 10mm Auto, but currently limited to:  38 Special, 357 Magnum, 40 Smith & Wesson, 44 Special, 44 Magnum, 45 ACP, and 45 Colt.

I'm sure a call to Redding would tell us where these 10mm Auto dies are in regard to future availability.  Though don't bother trying to call them now, as their answering system says they are currently shut down for 2 weeks, and won't be back to answer phones till Monday August 13th.

I have two sets of 40/10MM dies. One set of RCBS and one set of Dillon carbide sets.

The RCBS sizes to average of .4185 and the Dillon to avg of .416. In my experience Dillion dies always seem to leave a "hourglass" case. I don't like the look and feel it overworks the brass.
