Terry - "Nimrod" was a Francotte tradename. The barrels are Fluid Steel, likely Acier Cockerill of Cockerill Ougree-Liege.
Manufacture dArmes Feu Ligeoise used this steel almost exclusively, and labeled the steel Acier Universel. Some Browning patent Fabrique-Nationale-Herstal very early versions of the A5 shipped to the U.S. between 1903 and 1909 are marked Cockerill Steel. And Ithaca used Cockerill Steel for Flues No. 1 Special grade double for a period.
The gun was proved for a maximum 12g load of 1 1/4 oz. / 3 1/4 Dram Eq. (1220 fps) but the usual service (using) load was similar to today: 1 1/8 oz. 3 Dr. Eq. (1200 fps). The almost 110 year old wood would likely prefer 1 oz. target loads however.
Please have the gun checked and cleaned by a double gun specialist.
Thank you for the information!
So now this raises a question about reloading, I have been looking for loads that develop around 7,900 PSI, in looking at some of the reloading data there are loads that are in the pressure range that have velocities at and over 1200 FPS, so regardless of pressure are Dram eq always dependent on velocity? In other words should I be looking for loads below 1200 FPS, and not really worry about pressure, or should I be looking for both lower velocity, and pressure?
Thanks again!!
