[QUOTE="longbowelk, post: 1895830, member: 41272"] I am working on getting my 280AI off the ground you might say. I've been fireforming Hornady 280 brass and doing a 2nd firing with midrange AI loads. Prior to my last session I was prepping the 1st fired rounds that yielded me the headspace of 2.116 to 2.118. I resized and primed them and prior to powder and bullet I checked each one to make sure they would chamber. All passed that test. Next I put the powder and 162 gr Hornady SPBT bullet in just off the lands about .020. Now comes the problem. All the rounds were successfully shot and yielded a final headspacing of 2.117 to 2.1175 except one. See picture below showing the loaded round that would not chamber next to a successfully 2nd fired casing. When measured with the Hornady headspace tool it still shows to be 2.116 where it started. I am not sure but it looks like a false shoulder may be showing. Also, the shoulder looks messed up . Is it possible that when I rammed the bullet in the brass, the die possibly caused the false shoulder or the sort of flattening of the shoulder? I am using the Redding 280AI dies along with the .014 Redding competition shell holder. [/QUOTE]
