Finally did it, got some 308 W brass mixed in with 308 ME brass and FL sized to 308 ME. So I can still load the improperly sized 308 W and shoot in 308 Win AR? I am assuming the brass will fire form and then I can do it correctly. SAAMI specs say the ME shoulder is set back about .030. Cases reloaded 3-4 times but still look good. Will pushing the shoulder out weaken it to an unsafe condition?
