If its the heavy/bull bbl version, it will weigh around 9 lb...I have one in 20 bore.It must weigh all of that with the scope.
Had a ball mould made.
It was very mild to shoot, but I don't know what pressure.
I just used a very mild 1oz 20 bore load for the -7/8th oz ball,petals cut off the wad, some home made felt wads,then the 20 bore ball pess fit into a remmy case, nocrimp, sealed with blob of crisco.
I'll have to end some to Tom Ambrust
good luck
