I want to load for about 1800 fps. I have read about 16.5 grs for H110 on this forum and that goes well with what I have learned with jacketed bullets. The only thing that I worry about is sizing down the 312 bullet to .309. I guess everyone is doing it, but I always heard that excessive sizing was harmful to accuracy. These are just my thoughts. What are others experiences?
