I have been playing with a mdl 1892 french ordanance revolver and would like to report some cartridge building success.

In case anyone else out there has one of these old beauts sitting idle I would like to report that they are fun to shoot and accurate.

I used Starline 32-20 brass trimmed down to 28mm, a cut down lee .308 trim mandrel and a drill worked good.

I then ran them over .323 ball and then over a .330 ball. After opening up the neck the brass measured exactly 27.5

Loaded a .330 diameter jacketed 100 grain bullet over 3.8 grains of unique, fired by a CCI sp primer.

After the first firing the brass looked handsome and required just a little trimming to get it back to exactly 27.5mm.

After 3 firings the case mouths are fine.

I tried as much as 4.0 grains but that was a little more snappy then needed for plinking. 3 grains would not push the bullet out the barrel.

No chrony data yet but that will happen.

vive le revolver:D

David,
thanks for the great information. I also own a Mle.92 (mfgr. in '94), in great condition. I've acquired a die set (CH-4D), cutdown 32-20 brass (from Buffalo Arms), and 100 gr. TMJ bullets from Graf & Sons. I was planning on using Unique powder, but needed some reliable info. to powder my cases. This is precisely what I needed to know. Thanks again.
