interesting question. I just loaded, a 34 gr dogtown bullet from midwayusa over 25.5 grains of Benchmark. This is basically a starting load. Have not had a chance to test them out yet but if it shoots good I am going to stay with this load. My other option for powder is H-4895, it will get tested next if results are not what I want with benchmark. These will be my first reloads for the 204 as small rifle primers were all gone for most of this past year. Good luck, with what ever you go with.
