I recently purchased a used Sharps 1874 replica in 45-70 made by Pedersoli, imported by Uberti, and it has Stoeger Accokeek MD on the barrel.  This is my 1st replica gun which was bought for my son to use.  I reload for several modern firearms and thought I would reload for this one also.  I read on some other BB where I could safely use the 1895 Marlin loads in the many reloading guides.  I selected IMR 4198 and a Hornady 350 JRN bullet.  I loaded some bullets using the IMR data, using the lowest setting, which resulted in 47 gr.  After I was finished, I looked in the Hornady data and the lowest setting shows 32 gr. with a max of 45.3 gr.  When I went to the Pedersoli website, it shows that I should not use anything but the Trapdoor loads.  Given that I do not want to blow up my son, can anyone help me with all of this conflicting information I have.  Thanks.

JRN = Jacket Round Nose? Why?  If so, you are starting off on the wrong foot.  Use lead cast bullets only!

John Boy,

I am sure I got off on the wrong foot, but I suspect it has more to do than just with the choice of bullet.  I selected these bullets because it was what was in all of my reloading manuals.  But why only cast bullets?
