I have used all of my IMR 4198 powder and can't find any close to me, but I did get some H 4198. I am shooting a Savage with a 45 caliber barrel and was using 56 Grs. of IMR 4198 under a 200 Gr. bullet.
Imr 4198 and H 4198 are very close in burn rate can I use the same charge weight of 56 Gr. with the H 4198? Thanks, Oldsnow.

I have used both many times, H tends to shoot a little faster at the same weight.

I never saw much difference in my lighter loads. Some have said there was a fair amount of difference but I think they shot stout loads.

Just shoot it and then you will know?? It will not cause you any "dangerous" issues! I have used them both pretty much interchangeable!
