Guess I found mistake on this page.
"double 24in barrels of 32 bore (.56 caliber 1747 grain bullet)"
.56 caliber it's about 25 gauge, not 32 "bore".
Then 1747 grain bullet it's extremely heavy bullet and this particular double rifle doesn't look so heavy and barrel thick to be ready to fire such a heavy bullet.
I guess 747 grain bullet would be about right.
