As long as you use the Trapdoor data of Hodgdon's site and not the other .45-70 data you'll be fine. 1200 fps is below minimum velocity for a cast 300 and IMR4198 though. Starting load is 33.8 grains at 1,649 fps. Look at H4198. Gives slightly lower velocities.
The front sight blade is just a piece of brass bar. Gunparts likely has the proper blade, but so will a Metal Convenience shop.
