Original Low Wall 32-20 pressure question
I picked up an original Winchester 1885 low wall made in 1888 in 32-20. I'm currently loading 115 grain bullets over 17 grains of FFg goex or about the same triple 7 with a .030 wad. does anyone know the pressure of 32-20 black powder? I am also looking at loading smokeless in this action. specifically HP-38 which I have on hand. hodgdon load data says starting load at 3.2gr for a pressure of 11,100 CUP, looking up the triple 7 load data from hodgdon 18 grains they put at 12100 CUP. I know there is more going on then just the peak pressure but would that load of HP-38 be OK for a low wall rifle. I plan to mostly stick with black powder but am working on a poor accuracy problem and want to avoid black powder fouling before I decide if I want to have a barrel liner installed.
Thanks for any info.
