[QUOTE="westcliffe01, post: 798373, member: 35183"] I don't believe that science supports getting an extra 150 fps from 1 grain of powder... There are really 2 things left to do. 1) try moly coated bullets. These will initially lower pressure due to reduced drag and then you will have to add powder to make it go faster. But NEVER use loads for moly bullets on uncoated bullets ! Thats a recipe for a blowup. 2) If your magazine will allow it (or convert to a single shot adapter), seat the bullets longer. Seating longer increases powder space and lowers pressure, thus you can add more powder. This will not work if you are already loading long and then jamming the bullet into the rifling. In that case you will need to get the throat lengthened to allow seating further out if feasible. Its a slippery slope, since a longer throat will mean you can no longer shoot lighter bullets well. All of these points are discussed in detail in the Berger reloading manual. If you don't have one you should get one. It took those guys a long time to learn all this stuff and without their knowledge some of us may never "get it". [/QUOTE]
