0.357 Mag. 140 grain TC lead bullets. GM hard cast.
Using N320 / N32C.
MV not to exceed 1150 ft/sec.

Does anyone have load data for the above combination of components.
Looking for a load for indoor range.

currently using 3.9 grains N320 & 4.9 grains N32C behind a GM 158 grain TC lead bullet.
Gives MV of around 1125 ft/sec & 995 ft/sec respect.

Thanks
Regards
Al.
