It's an old thread, but I trim all my brass to 1.515.( My goal was to trim once, then never again over the life of the brass, I thought 10-12 times would be all) Back then( 2008) the wolf brass would stretch to 1.560 on some. I used 1.515 as a standard. Now ( 3 yrs. later), I've measured some older AA brass= after 12-14 reloads, and it all chambers fine, I don't even measure them anymore, just toss them in the chamber to test function=(good to go, or not) ... although it's time to take up annealing those old brass, as they don't hold neck tension as before. That's not because of neck length. Rasp 65 explained long ago how to test your chamber, for brass OAL's. I tried it and mine is 1.536. IIRC. This is a low maintenance round , if it's not hot-rodded.
