I have posted this on the reloading form but haven't gotten a replay as yet. I have gotten all the things I need to reloade for the 45/70 I have hornady 350gr. interlocks and some Speer 400 gr. flat points. The Hodgdon manual lists the 350's at 1786 FPS at 21800 CUP and 2013 at 29500. The speers are listed at 1845 at 25000 CUP. The rifle barrel is marked max pressure 2200 bar whith I think is 31900 psi (14.5 per 1 bar x 2200) would that be right? If it is I would have a hard time deciding whith one to use. the RP 405's shoot very well but are a little on the slow side for what I want I doin't know if the others are to hot but the manual lists 385 cast at 1805 for 21800 in the trapdoor so the 21800 in the 350 should be ok I just doint know abut the 2013 load. I have herd that in the 45/70 and some others cup and psi are the same is that right? thanks
