Both the H and IMR 4198 are my favorite in 45-70. Works good reduced and works good for full power loads. Also plays well in the 30-30 with cast, good power, consistant and a pound goes a long way.
For 223, I routinely use 21.0 gr. of imr 4198 for 55 grain fmjs. for the kids to shoot. I use it in 45-70 also, but do not remember the number of grains. I use it with the Ranch dog mold,..I think it's a 350 or 360 grain bullets, I have not tried it in 444 yet. But intend to if I can find some data for it. I do not shoot the 444 much.
My favorite load with IMR 4198 is for my 30-30. The 174 gr. Lachmiller checked, pc'd, and sized to .311 over 20.5 gr. IMR 4198 . It is a deer slaying load. I also shoot alot out of my Rem .222 788 bolt gun. Jackets as well as cast with great results. - Caster
In regards to shooting safety.Until you are ready to fire, keep your booger hook off the bang switch.
I use it in 45/70, 444marlin and .458 SOCOM as well as cast bullet powder in many bottle neck rifle rounds
