i got a lb of h-4198 for cast bullet/plated loads in 30-30....
and shortly i may be acquiring a m77 .204 AND a rem 788 .308.....
i see some data foe the imr 4198 and none for h 4198...
although they are one on top op the other on burn rate charts, imr is a bit slower i guess....
could i reduce loads of h4198 to substitute in for imr4198 most likely ONLY for the .308 and 30-30 though, i got some varget for the 204lol.
mostly im wondering how close to being interchangeable are h4198 and imr4198....
