H1000 and IMR 7828 should be about right. Since the bullet base will likely be well into the body and robbing you of case capacity, I would try 7828. The Hodgon site says to start at 50 grains. In a factory 22-inch barrel I am betting you will be lucky to get 2700 fps but interested to know what the actual velocity and accuracy is.
