Question about high-volume cases designed for Cordite

[forindooruseonly]

I hope this isn't a stupid question. Supposing you have an older double rifle in an old elephant caliber - something like a .450 #2 Nitro Express, which was originally loaded with sticks of cordite.

How would one go about working up a load that had sufficient powder volume to prevent hang-fires, but remained on the low end of the pressure scale?

Is it possible? What are the options, if any?

There is load data for all the old smokeless double-rifle calibers using modern smokeless powder.

You just have to dig for it.

In general, they will use the same or slower powders as heavy load 45-70, and there will be no danger of hang fires.
