[QUOTE="MagnumManiac, post: 2546112, member: 10755"] This nonsense about brass stretching on the first firing RESULTING in case head separation is so far from the truth that it begs belief. The case does NOT stretch rearward, the shoulder blows forward and brass is pulled from the neck to fill the void…the ONLY way case head separations occur is if the loader then moves the shoulder back. What you should do for the first THREE firings is to neck size to allow the case to FULLY fill the chamber, then, and only then, should you bump .001” with spring back. I can load my comp brass dozens of times without head separation occurring…wonder why? Cheers. [/QUOTE]
