I'm loading 75.5 grains so of H1000 under 220 grain hornady ELDX bullets. I'm trying to find more load data for the 220 grain ELDX rounds using H1000 powder. This load is shooting groups at 200 yard you have to really look at to tell it is more than one bullet. I have them seated long enough it won't load out of a magazine so I made a single shot adapter for it. I have shot it out to 500 yards and got under 1.5 inch groups. I don't know if i'm at max charge or not. Don't plan to change the load or anything, just looking to find more data on using H1000.
