What are your opinions on using a Federal MAGNUM primer for the following load? Brand new Henry lever-action rifle and brand new Uberti 1873 Cattleman revolver- I've heard the frames are both stronger than the original 1800's ancestors but still not anywhere near Ruger Blackhawk.
Here is Hodgdon's data for my powder and bullet, but not for the magnum primer:
200 GR. CAST LRNFP Hodgdon Titegroup .452" 1.600" 6.5 933 9,300 CUP 7.7 1050 12,700 CUP
Where do you think I should start?
