I recently bought one of these little rifles in 7.62x39 and would like some info. As I understand it the barrel is 30 caliber yet because of the way the forcing cone or throat is designed .311 dia bullets can be fired through this barrel. Is this correct?. Getting back to the 30 cal barrel. can one also shoot 30 caliber bullets as well. I'm getting some of the PPU Serbian made x39 for starters and brass. I realize I need a three die set and would like both expanders for both .311 and .308 bullets are these two expanders included in the set (Redding delux) 3 die set. I also have some 7.62x39 as loaded in Israel by the old Hanson Cartridge company and some 124 grain Lapua Finnish ammo again for fireforming and help to break in the barrel. The Finn ammo was deleloped for the Valmet and ak type rifle being brought out when the finally ditches their moisins and usually the Lapua brass is excellent. Any help is greatly appreciated. Thanks Frank
