I'm looking into reloading some .45 Colt ammo. I got the Lyman 49th reloading handbook out of the library and found the load data for .45 colt. Sadly, they do not list any data for shooting roundballs. I emailed hodgdon asking for load data, but they said they had none. If I search online I see people giving data, but that seems a bit shady.
I found data for .45 colt here and the trend seems to be that the smaller bullets have more powder so that would make sense if the max load they are listing is simply a fully filled case with no compression.
Does anyone have any experience with Trail Boss as to if the max loads are always filling the case with no compression?
