Here is the load data that the former owner worked up with Cal Pappas,  author of The Double Rifle Primer, The British Bore Rifle, and The .600 Nitro Express.


Reloading data with a 700-grain ball:

70 grains of Blue Dot or 220 grains FFFg (3F) black powder. Both loads will give 1550 to 1600fps.

Easiest way to reload is to buy a single stage MEC 10-gauge press with a short kit for 2 7/8 cases.

You can deprime, prime, add powder, set the over powder wad to the correct pressure.

Then add spacer wads by hand and place your projectile in the case

Crimp with Buckstix tool

For spacer wads, punch 3/4 diameter felt wads from carpet backing felt in any flooring store

Or use Remington SP-10 shotshell wads and trim off the shot cup petals
