I want to experiment with Trail Boss for use in my .357 Mag 8" DanWesson for use in Handgun Silhoutte Field Pistol using .357 Mag brass.
In looking at the IMR website I find the data listed does not make sense to me. The max load for .38 Special 158 gr LSWC is listed as 4.2 gr delivering 804 fps and 13,700 CUP from a 7.7" barrel. The max load for the .357 Mag 158 gr LRNFP is listed as the same 4.2 gr delivering 865 fps and 20,400 CUP from a 10" barrel. I've been reloading for 30 years and this data contradicts my experience. Any insights or suggestions would be appreciated.
