I found online that you can fire form your brass by filling a whole case with Bullseye, measuring that volume by weight and loading your brass with 10 percent of the total volume. Has anyone tried this and does it work? The instructions say to do it again if your case does not expand enough. Has anyone used this recipe? Should I make it 12-15% to ensure an expansion? I'm fire-forming 30-06 to 7.7 Arisaka brass. How far will that wax plug go in distance? Thanks
