Wow, that's significantly longer. No wonder you blew the end of the case off! Perfect for using the Lapua 47mm cases, 30x47. Now that I think about it, that cartridge would qualify for a "hunter" class rifle, which must have the case capacity of a 30-30. People have made wildcats for years to make those. But the rifle itself has a 3" wide forearm doesn't it from the looks of it. For a hunter class it can't be over 2-1/4".
