7.65x53 Brass Forming

[abunaitoo]

Had the same problem with the Lee dies.
They just don't seem to size enough to use as a forming die.
The RCBS dies had no problem.
For reloading, the Lee die work great.
No idea why this is.
I use 30.06 or .270. Both work fine.

I have Lee dies and they DO NOT size enough to make cases work in 4 Argentine Mausers. They are about .010 longer than RCBS dies in the same cal.
I also have 4 RCBS FL dies and a RCBS trim die and they are all exactly a match for the Argentine chambers.

I have made several hundred 7.65 Mauser cases from USGI 30-06 cases with the SL-54 headstamp. None of the necks are too large for my 4 rifles. These are 3 1891s and 1 1909 rifle.

This mirrors my experience as well. I chose to remove material from the shellholder instead of the die itself. It worked after a fashion, but I still wasn't satisfied. I found a set of CH dies and never looked back.

The comment about the Belgian and Argentine cases being "different" triggered a memory. I was using actual Argentine surplus brass, priming with Berdans and ran into a screwy problem......the cases wouldn't fit in a standard shell holder! I tried Lee, RCBS and one other with no luck. I finally ordered a shell holder from CH4D and they slid in no problem. Moral of the story? Things aren't as "standard" as they seem...........
