I had previously listed these as 6.5 x 70 R cases but that was incorrect. 6.5 x 70 R is the case these were used to make.
These are new Bertram in a straight basic case. I was told this is the case to use to form 28 x 30 Stevens. 
I am selling these for a friend that used this basic case to form brass for a drillings he had with one barrel chambered for the 6.5x70R.  The dimensions of this straight basic case are,
length --- 2.821"
rim diameter --- .418"
head diameter --- .354"
diameter at mouth --- .350"
rim thickness --- .057"
I made these measurements with a dial caliper so may be off by half a thousandth either way.
There are two boxes of new brass but one box is missing one round so a total of 39 rounds of brass.
They are priced at $5.00 per round.  I can ship all for $13.00
Please PM if interested.
