I've used 4895 25 years ago in a 243 and really liked it. I'm going to try it in a 204 but I'll be using IMR4895 because thats what my dealer stocks and thats what I've been using. I know H and IMR 4895 are similar but I really know the difference. I just don't mix the two. I think its a good all around accurate powder. I've also got some of the best groups out of my 243 with it. Good luck and have fun.
