[QUOTE="Blackhawk, post: 1897264, member: 105459"] Question: Have you annealed any of your virgin or once fired brass? Brass is softer than you chambers wall and will conform accordingly. Your brass shells forward momentum is stopped when shoulder shoulder to chamber wall is experienced. This in turn places stress on your case necks and eventually will lead to a molecular hardening of brass. Let me qualify my last statement. Each manufacturer of brass shell cases whether for pistol or rifle will use different materials in different amounts during the manufacturing process. This will mean that different brands of brass even in the same caliber are not entirely equal because of the manufacturing process that they are use. [B][I]I have encountered the same issiues that you are talking about and this is how I overcame them ![/I][/B] After decapping , using a universal depriming tool , and deburring the inside of your cases flash holes examine your cases for any defects. then please continue reading.
