I would have to pull a bullet and weigh that powder.

VV doesn't list data for the .32-20, but they do for the .357 mag., which has virtually identical case capacity. A .357 with the 110 gr XTP uses 18.5 to 20.8 of VV N110, with a 7" bbl. With that info, I would not feel trustful of the info written on the box - It just shouldn't feel right that the rifle would shoot that hard with that load.

Is the charge really 10.2 gr., and is the powder really N110?
