Picked up what is supposed to be a Beretta DR in this caliber. Guy said it was a 45-70 but once I got it in, saw the barrel was stamped with this caliber designation. Haven't cereosafed the chamber, but it appears to be a case between the 45-100 and 45-110 length. Any information would be appreciated.

I seem to recall reading in an old Gun Digest that Elko Arms was a company that converted Beretta shotguns into double rifles in .45-70 caliber.

Try doing a chamber casting or ask in the wildcatter forum. I've never heard of it. but it should be a nice one.

edit;
You got me gurious,, I googled and found that Gun's Magazine had a piece on it in 1995.

"45-70 Elko Magnum Bodinson, Holt September 1995 .45-70 Elko Magnum A custom rifle chambered in an enhanced version of the classic govt. round. "

Did a chamber cast. Case is 2.6" long, .500" base,so I am thinking 45-100 Sharps.

No. The .45/70 Elko Magnum is a standard European cartridge normalized by CIP. Case length is 2.598", max pressure 42,786 PSI.

You'll find the CIP specifications here:

DON'T try to scroll through the thing, as it takes forever. Just click on the above link, let it load, then print page 104.

Thank you for the information. Been looking for case dimensions. It is almost identical to the 45-100 2.6" Sharps. Rim dia. and thickness and case head dia. are about .005" smaller on the Sharps case. Nice it has a 1-20" twist.
Gives me an idea of what cartridge the gun is chambered for. Much appreciated

The good news is that CH4D shows dies @ $104.

Any time, Rockrat.
